Please watch: "MY NEW R35 GTR!!!" https://www.youtube.com/watch?v=OBAdmy1M42Y --~-- In Pt.6 of the LAMBO KILLER BUILD | 600HP AWD TURBO HONDA CIVIC - I made an attempt to modify the existing harness for some aftermarket sensors and ended up shorting the signal to ground and lost the 5v output! Meanwhile, Dave took the whole harness apart and figured out what I did wrong! Now the car is going to have a super clean tucked harness!
Alright guys, back at the shop working on the Civic again today.
This is part six of this build.
So as you guys seen in yesterday's video or two days ago video, we did get this thing
actually fired up.
We got the complete Detwerx fuel system installed.
We got all the K-Tune parts installed right here.
And we also got the engine actually running by itself on the E85 with the ECU master connected
to this harness.
So I did have to change the injector plugs over to the Detwerx style.
And as you can see, I have a fuel pressure sensor right here.
And we have a couple extra sensors on the engine that we're not actually using.
So ECU master EMU black has a built in five bar map sensor into it already.
So you basically just run a vacuum T right to the ECU and you don't have to run an external
map sensor, which is really nice.
And that ends up saving you, I don't know, probably like 60 to 100 bucks in an extra
sensor.
But yeah, so we have these two map sensor plugs.
There's one on the throttle body one right here.
I basically just have them plugged right now.
And you can see this is the plug that actually goes into them.
So I was probing around a little bit.
So this has a five volt signal, a signal reference and then a ground I'm not sure in the in the
correct order.
But this one does have five volts right here.
And this sensor does take a five volt a ground and then a signal that goes to the ECU.
So what we're going to do is we're going to backtrack this one back around up through
this harness and then back down here to the oil pressure sensor, aftermarket oil pressure
sensor just like this.
And then down here, this is the charge harness that goes to like the knock sensor and everything
it plugs into this harness right here.
So we're going to actually use this one for the fuel pressure since it's already down
here.
That's a three wire plug as well.
We're basically going to go right up here to the bottom and up through the bottom of
the intake manifold right there.
So that's going to be our fuel pressure, we're going to have oil pressure back there.
And then right here we have this EVAP solenoid.
And so one of these sides right here, that one, this one has 12 volts on it.
And that's what we need for our boost, our four port boost controller.
So one side gets 12 volts all the time with the key on and then the other side is a pulse
width modulated ground.
So I'm going to go ahead and cut off this plug and extend it down a little bit and we're
going to run that to our four port boost controller.
And so basically what I'm going to do is going to go back and probe through the harness right
here for the map sensor plug.
We're going to come over here to the factory plug right here, which is probably the A or
the B plug.
One of these will be the map sensor, probably the ground and the signal.
And so what we'll do is we'll just take the signal and we'll tap into that for the fuel
pressure and then we'll find the ground or maybe we'll just ground it somewhere else.
We should be able to find the ground because it doesn't actually have a ground right now.
So ground needs hooked up to that, but, and we'll run that to the ground for it.
So lots of little wiring stuff right now.
It is one o'clock in the afternoon and we are planning on being on the dyno at PFI speed
tomorrow sometime.
So today's Wednesday, 1pm, so we have less than 24 hours from when this car needs to
leave to go to the dyno.
So obviously we've got to do radiator, we've got to do intercooler pipe, we've got to get
the turbo, we've got to get the wastegate, we've got to get the exhaust and everything
plumbed.
We've got to get the brakes bled, we've got to get the clutch bled, we have to make sure
everything works.
We still have to hook up the driveshaft, we still have to weld in the thing, we've got
to install the rear axles, we've got to install the rear brakes.
We have a ton of stuff to do today, so I guess stay tuned.
Alright, so I just got done wiring this sensor right there, you can see the little looms.
The wire that I used is a little bit too thick so the little rubber things, the little seals
aren't working the best, but I went ahead and I put it in this like abrasion loom and
then heat-shrinked it down there and I heat-shrinked it up here too, so it kind of looks a little
bit prettier.
So I actually lost my 4-port boost solenoid.
Since we've been running around the shop doing, I've just been throwing stuff everywhere and
there's new parts everywhere and I just, I don't know where it is.
So I'm going to go ahead and wire this plug in for the boost solenoid and that goes to
one of the EVAP plugs.
And then right here, this is the MAP sensor plug that I'm going to use for the 3-wire
for the oil pressure sensor.
So what I've been basically doing is just taking all the tape and the wire loom off
of it and trying to pull it back so that that way I'm not using, you know, bringing a wire
over here and then just backtracking it all the way on top of the harness.
I think it would be kind of cool to actually get it to go inside this harness, like if
I could pull it back far enough and it has long enough wire to actually pull it up in
here, keep it in this harness and run it down just the back of the engine right over here,
right next to all the VTEC solenoids and everything and basically pop out right here where the
other oil pressure stuff is anyhow.
And so that's kind of the plan is to kind of get it over there.
So maybe I'm just going to go ahead and pull this thing out of the car now since I have
that sensor wired because that's a pretty simple one and it'll probably be a lot easier
to actually do on the ground.
Okay, so I've been sitting on the floor for a couple hours now it feels like.
So you can see we got the ECU master black, I have all the wires and everything pinned
in here, pinned into there, this is my little auxiliary jumper harness that kind of ties
in some other sensors like the wideband and a couple other little things like that and
a couple other little, I guess some other stuff that needed to be tied into the E-plug.
Basically everything's all wired so instead of having the little jumper harnesses for
the grounds and everything, I tied those into there and there was another plug on here that
had power so I ran that to the ECU power.
I went ahead and I wired in the oil pressure sensor, we have the, this is the boost sensor
right here, the fuel pressure sensor ties into that harness right there and then we
also have the intake air temp sensor which that obviously was already in there, extended
the wiring for the TPS and yeah, did the injectors.
I wish I would have had this lume out yesterday, I didn't think I had any more left, I wish
I would have did it on there but yeah.
So I ran the harness for the map sensor harness, I converted that to the oil pressure harness,
ran it through here and it's coming out back there so I should have plenty to plug in the
oil pressure sensor.
Kind of just cleaned everything up, zip tied it all back together and everything should
be good.
So I guess the order of operations for getting like the oil pressure sensor and stuff is
I just stuck in the little wire tester right there on the little beep mode, stuck it in
there, matched the wire color over here, beeped it and then did the input on the ECU master
so you can see like right here, I did the oil pressure sensor to analog in number one
so I came over here and where, where's analog one?
So analog in number one so it went to B31, same thing with fuel pressure, boost pressure,
all that type of stuff.
I don't think we're going to use ethanol on this one for now but if I do that later I'll
just tie it into this harness.
So that's, that's pretty much it for that, I'm going to go ahead and lay the harness
back in the car and start kind of routing this stuff and actually taping and zip tying
this stuff back up together, getting it laid out nice and then I'm going to fully wrap
it and then go ahead and stuff that in the car.
So we are super super close, we're pretty much ready, move on to the next like ten things.
Alright so I went ahead and installed the harness on this thing, I got it wrapped in
this like 3M fabric tape, they call it friction tape, whatever that means, so I don't know
if it's good for heat or not but I'm definitely going to wrap all this stuff in heat stuff
just because it is so close to the turbo manifold, you can see I was kind of mocking up the turbo
real quick, this is the turbo off of the sleeper which I feel bad because that thing just got
robbed, it got robbed of its E85 last night, it got robbed of the turbo, so I need to clock
it because right now it's completely upside down and the housing is pretty, pretty tight
in there but once I get that clocked I can run the oil drain line and I can run the feed
line and then I can start actually mocking up some sort of a down pipe or up pipe or
whatever exactly we're going to do on this whole situation.
So we have been thrashing on this thing for a little bit longer and you can see we got
the radiator hoses all hooked up, we got the radiator in here, made some mounts for the
bottom and then Koyo supplies these little mounts right here but this is for an EG or
an Integra so I did have to kind of drill a hole and then kind of modify the bracket
but it's rubber mounted right there so it has a little bit of wiggle in it.
I went ahead and I got a SPAL 12 inch fan that's really, really low profile so that
should be good and this radiator is a cross flow so you can see how it's welded right
there so the water has to flow out of here, over there, down and then back over to here
or vice versa so the fan is going to touch, it's going to cool it no matter what and plus
you know most people run just a half size radiator on these guys anyhow and they're
fine with that, this is just going to give us some extra cooling capacity.
So now we have, right here we're going to take a little 90 and go down for our intercooler
pipe, we have the turbo all clocked basically where it needs to go.
I spent a long time clocking this thing and tapping the holes on the bolts and doing all
kinds of stuff to try to make it really solid so we have the oil drain which is hooked up
right there going straight down, we bled the clutch, we need to tighten the bolts down
for the back so we need to fab an up pipe of some sort, we have the wastegate mounted
back there and I am going to be using these push lock fittings which you can't really
see that but yeah you can see the wastegates back there so we have just a tiny, tiny little
bit of room for the heater hoses so I'm going to probably plumb those into the actual core
real quick and then I think we can actually fill coolant in it and actually start it after
I hook up the oil line so we have to, hooking up the oil line over here to the factory oil
pressure sensor with an AN line going over there so I'm going to hook up that stuff too
and then we can actually fire this thing, let it warm up and do all that type of stuff,
probably drive it but it, update on the dyno, so it's 1.30 in the morning, we were planning
on going to the dyno tomorrow at probably like early afternoon or something like that
so I'm probably going to thrash on this thing for a couple more, maybe like another hour
and a half here tonight, stay here until 3, try to get down here early tomorrow with the
trailer and everything, try to finish everything up other than the driveshaft stuff and then
head up to PFI and hopefully get it tuned tomorrow night, street car takeover is on
Saturday so we have lots of stuff to do.
Alright guys, so kind of have a little bit of bad news, it is 3.50 in the afternoon,
I've been here for a couple hours trying to diagnose a wiring issue that I caused and
I don't know exactly what happened but last night I put this harness in here and we basically
tried to start it, we put the TPS off of the type S on there so I got on the computer,
plugged everything in and was looking at it and had Ty kind of adjust it just to see,
just to change the voltage because I did scale the voltage at like 1.7 volts to get it to
read zero because the CRV, TPS was clocked way differently so it was already stretched
like halfway so to make it read zero when it was at zero I just scaled the voltage up,
so then I scaled it back down and then tried playing with it and no voltage at all coming
to it so I was like okay well let's see if these plugs have voltage.
So this is yellow and blue, that is a 5 volt signal, the green and yellow that is a sensor
ground and then this is the sensor wire that goes back to the ECU to tell it the TPS percentage.
So we started beeping around, I connected just like this on the inside of the ECU, connected
to that 5 volt signal, came out here, it beeped just fine, connected it to this one to the
ground and it beeped as well.
So I think I, what happened is the 5 volt signal shorted to ground somewhere.
I'm not sure exactly where or why or what exactly happened with it, the only thing I
could think that maybe happened is when I had, when I was trying to plug in this plug
yesterday but I don't think they would really touch.
So I didn't have the little plug thing on here, that's the only thing I could think
is that these things touch kind of but I didn't have the little cap thing to go on it but
other than that I don't see any other way the, I don't know, 12 volts got to the 5 volts
or the 5 volts shorted to ground and so the ECU is actually not producing 5 volts anymore
so Dave is over here messing with this thing and I'm going to wire it up on the bench just
to see what exactly is going on.
We're going to try to see if it has a 5 volt output when we connect it to the ECU.
So taking out all the other sensors and type of stuff just to see if we can actually get
it to work to give us 5 volts because if we get it 5 volts and we leave these sensors
unplugged we might be able to make some stuff but I don't think we're going to be making
it to the event unless some miracle happens because I still need to do intercooler piping,
I still need to do exhaust, we still need to hook up the axles in the rear and weld
the diff mount and everything so things aren't looking so hot for the Civic.
Alright Chad give us a run down, so the harness is back out of the car.
So the harness is out of the car, David is going crazy on this thing, he's going to figure
it out and we went ahead and pulled apart the actual ECU, the ECU master and there's
two little super super teeny tiny like fuses in there and they were both popped for the
5 volt signal and so if we could figure out this wiring we could jump over that and kind
of bypass it with some solder and hopefully this harness works, if not I think what we're
going to do is we're going to steal the harness out of the type S and we're going to take
apart an ECU, we're going to make a jumper harness to the ECU master and then from those
plugs basically I have another set of plugs from the Supra so we'll basically make a jumper
harness that plugs into stock ECU connectors so that we don't have to mess with anything
and then worst case scenario plug in a PFI for the weekend and then go back to ECU master
after we figure out this whole situation so that's if we can't get it working.
The other thing is I guess we'll take the Supra street car takeover, I thought about
taking the ECU out of the Supra because it's on the EMU black as well but I don't want
to fry it as well so we'll see.
While Dave's messing with this wiring harness real quick I'm going to go ahead and throw
in these axles just so like I can actually set the car on the ground, put the brakes
and everything on it, we'll do the drive shaft later but I'd like to actually get it to where
if we do get it running we can back it off and do all that type of stuff so I need to
throw these axles on, a lot of people were mad because I was just going to cut and weld
the stock axles so in the Wagovan or in the RT4WD wagon one of the axles is long and one
of the axles is short and it's kind of a rare pattern to get like you can't just go to O'Reilly's
and buy one of these so in Sane Shafts they have a set of 500 horsepower rear axles which
is the same ones that I have in the front and basically I just ordered two of the left
hand drive ones, the left hand ones on the car which are both the long ones so I'm going
to go ahead and stuff these in the car real quick, put these arms right here.
Alright Dave, so you've been at this for about three hours, Dave says he's about almost done,
do you guys believe him?
I'm excited, so what have I done wrong so far Dave?
I mean I haven't really done anything.
You haven't paid attention, that means I didn't do nothing wrong, how about that?
I just have been fixing this mess.
Can you tell them where you're going to run it?
David and I got to beat that out, so Dave says he's about done, Dave says he's about
done over here, Trevi just got back from dinner and Trevi got the rear brakes and all that
rare stuff going on.
This is almost done to Dave which looks bad but it really is.
So Dave is actually going to run the whole harness through the top of the valve cover
right here, so everything is going to be right here so we're not going to have to go under
the turbo, everything is just going to go up right there, which is going to be really
nice.
It's going to be nice to be away from the heat a little bit.
And then now, there's something missing right here Trev, what do you think?
Oh like intercooler piping?
Yeah.
We should probably get to that.
So let's get to that yeah, because you can't make no choo choos without...
Can't do the choo choo boys without white pipes.
I made a button up the rear and then we'll get to that.
So Dave and Ty ran to Walmart real quick to go grab some zip ties and I think they went
to Sonic to grab some shakes too.
Dave's been down here for a little while, kind of messing with that thing and I really
really do appreciate Dave doing that because I don't know, I was just going to go crazy,
mess with that thing.
So the harness is going to turn out really good, it's nice kind of having him mess with
that.
And so I went ahead and I've been playing with the intercooler a little bit more, I
actually leveled it out, well it looked level to me at least, doing a little strap right
here for now, probably cut off that end and I could kind of adjust this in and out and
then we can make some brackets later but this is kind of getting her mocked up pretty well.
So a straight out of here, a 90 right there kind of coming down and we're going to kind
of 90 it again and then go back around.
So kind of the plan is to, maybe I could probably actually get away right here with like a 45
and then 45 it over, tuck it right here and then have this as the inlet, drill this a
little bit bigger so we can put a tube through there and you can see you've got a little
90 kind of going up, or going basically straight down there.
So we'll kind of clock that off to the side a little bit and have that come right around
here and go straight into the intercooler.
So that is, that's pretty much that, I did go ahead and I was working on the brake lines
back here so I got the rear brakes all in these rear trailing arms completely bolted
up, got the axle nut all tight, you can see I've got brand new stainless braided lines
going to these things.
I know everybody was upset about me letting them hang and stuff and that was kind of my
plan this whole time.
So yeah, all the bolts and everything are tight, tighten everything up on the rear diff
mount.
So man, it's like 10 o'clock at night, I don't know how this dyno did, if we're going to
make it or not, because literally, if we're going to do it, we'd have to be up there at
9 in the morning, which means we'd have to probably leave here at like 6.
That's not that much time, I have to fabricate intercooler pipe, we've got to start it, we've
got to run it, I have to do exhaust stuff too, we've got to bleed the brakes, we have
a lot of stuff to do, I'm going to start working on this.
So Dave's been messing around with this harness over here, Dave, what did I do?
You shorted the 5 volt at ground.
Where?
These two connectors.
So the coolant temp sensor, the IAT, they got it for some reason.
I gave them 5 volts, or 12 volts, I don't know, I shorted it to ground.
That's what happened.
Dave's cleaning it up, I'm playing with intercooler piping over here.
So I got this little section right here, basically you just need to kind of stick that on there
and weld it up, and that will be my output.
And then right here we have a 3 inch input, you can see that kind of goes down 45s right
around this edge.
I'll probably actually cut that off just a little bit, it's kind of long.
And then this should kind of suck back a little bit and give us a little bit more of a nice
angle right here.
But yeah, I mean overall for just, for literally just having stuff laying around like my, I
have a ton of intercooler pipes and stuff from all the random projects and stuff previously.
But for just stuff laying around I think that's pretty good for what it is.
I don't know if I should, I mean I should probably run a blow off valve, but I don't
think I have a blow off valve, I have this one.
I have that blow off valve, I don't know if it works though.
It looks kind of broken on the inside.
Those things kind of sound...
Where did you buy the tile?
I have a fake tile that I got a long time ago.
I don't know.
No, I got a new tile wastegate, but I didn't get a blow off valve.
He has this engine wiring harness just kind of chilling in the engine bay, getting it
all laid out, kind of zip tying clumps of it together, kind of putting it in where it
needs to go.
So he's messing with that.
I just got all the intercooler piping all buttoned up.
You can see we have an intercooler pipe going down there.
We have a tile blow off valve, we have an intake air temp sensor, it kind of goes around
the edges right here.
It was rubbing a little bit, so I went ahead and put this little rubber guy right there.
But yeah, super, super solid.
Looks pretty nice.
Dave's harness is going to...
Dave, do you think your harness is going to work?
No.
First start?
Guaranteed?
Sure will.
I hope.
I mean, it's going to look really nice, especially not running it back through that damn turbo
stuff.
All right, guys, four in the morning, dyno day.
We should honestly probably be like loading it in the trailer and driving.
Yeah, we should probably like, we should be loading it in the trailer right now and not
still wiring stuff.
So Dave's made some really good progress on here.
So you can see basically this whole side of the loom is pretty much kind of where it needs
to be.
And then, so right here, this is kind of the, the mess of stuff.
So basically, so from what I understand, you're just going to pull this kind of into the car,
get the length and then like, I mean, just put it in the car and just pin it.
Just pin it.
So are we going to cut them to length?
Okay.
Just using the pins.
So yeah, basically pull it, get them all in the same length, fricking lop them off, re-pin
them, pin them into the plugs and then turn the key.
Yeah.
What time do you think we'll turn the key?
It's next week.
You're thinking next week?
I was kind of, I was kind of thinking that that was almost when we're going to do it
too.
But, uh, so I finished the down pipe up pipe type of thing.
I reused the little hood stack that was on the D16 and I think that's going to line up
pretty well with the hood and it already has O2 bung and everything right there.
And, uh, yeah, two and a half inch for now until we get to a different turbo on here.
So I do have a 3582 coming, we just don't know when yet, but, um, then we'll do three
inch and we'll do some nice stuff.
So I was working on a waste gate dump tube and was getting that all kind of mocked up
and then I forgot, well actually I realized one thing and that's, uh, that we still don't
have a shifter in there.
So I have the cables from the TSX.
Those are hanging out right here.
And then we have the K-Tune shifter that is, uh, it's, I mean, it's just been sitting in
the box just waiting to go in.
So while Dave's messing with that, I'm going to pull out my center console right there
with all the shifter stuff and try to, uh, try to do that.
So we have absolutely just been thrashing on this thing.
Dave has been working on this, this harness for how many hours?
Since six?
No, 530.
Five.
Three.
No, noon.
No, it wasn't noon.
It was because that's when we got here.
She got here at noon.
You started, well, we were messing, like diagnosing stuff at like noon and then, cause I went home
for dinner at six.
You started at five.
So Dave's almost been working 11 hours on this freaking harness and, uh, I mean it's
turning out really nice.
It's going to be a nice, it's going to be a nice, nice harness, especially with it,
with it looped right here.
But console stuff.
All right guys.
So Dave, we got the harness all laid out in the engine bay, see all the wires are nice
and pretty exactly where they need to go.
And then he has them stuffed up in here, go all right up in there.
So they go up through here and then back out this side.
So basically the only wiring that we're going to have really showing is just this little
piece right here.
And we'll obviously put some, some sort of loom on that and then stuff it down through
a little grommet there and then we'll go to the ECU.
But yeah, I need to work on depending and doing all this other type of stuff.
I went ahead and I installed the shifter cables.
This car has always had a weird hole right there.
So I think technically the shifter cables should come out a little bit more under like
the heater core, heater core hoses.
But for now they are, they're right there and they are hooked up in here.
I actually need to put the pins in them and then it'll probably shift a little bit better
too.
So let me do that real quick and then I'm going to show you guys the shifter.
All right.
So shifter and everything is all installed now and man, that feels, it feels way better
than a D-series tranny.
So these are just the stock CRV cables.
The TSX cables, they're a little bit different, the mechanism and stuff and the way they mount
on the tranny.
But yeah, K-Tuned also makes a set of race cables too that are a little bit stiffer I
guess and help with shifting feel.
I'm going to, I should be able to get by with these cables for a little while, but if you
stretch the stock cables, they end up getting really, really hard to shift.
So it is 5.40 in the morning and I think, I think that's what we're going to call it.
Again, we need to, we would have had to have been basically on the road right now to PFI
and we still have, I mean, we have, we still need to wire the freaking car so, and so many
more other like little finicky like things like wire the radiator and bleed the cooling
system and bleed the brakes and just all that type of stuff.
So yeah, I guess we're going to, we're going to leave it at that for tonight or today,
this morning and we'll come back this afternoon and try to finish up some stuff on this and
I'll probably end up taking the Supra, I think, to the streetcar takeover.
So all right guys, so a little update, it is 3.21 PM, should have been on the dyno this
morning.
Obviously that isn't going to happen.
PFI is actually setting up a booth at the streetcar takeover.
They basically do a pre-meet at like a Twin Peaks thing.
So they had to be there.
I think they were leaving it, I think 11 or 12 or something this morning to go there.
So that's why we were not dynoing it tonight.
But yeah, so they're going to be busy with that basically for the whole rest of the day.
So that, that is going to be where we call it on here.
I went home, well actually I went home, I slept for like two and a half hours and grabbed
the Supra.
So there's a couple of things that we need to do to this.
I need to charge AC and do a seat and clean it up and do all that other type of stuff.
But that will probably be in a, in another video.
I know there's a lot of new guys here for the, for the Civic, but if you guys have not
seen my video on this Supra rebuild, this thing looked like, just go watch, go watch
the video.
I'll put a little link up here in the description.
But yeah, that I guess is going to be, is going to be it for this video.
I really wish I didn't mess up the harness because we would have been on dyno, we would
have been making some fricking power, but stuff happens.
I don't want to rush it.
I don't want to have any issues or, you know, there's just so many more like little tiny,
tiny little things I need to do.
But if you guys are interested in this project, be sure to subscribe, go check out the other
videos, the previous videos and subscribe for more for the next video.
So see you later.
