The Electrical Thread

[hondaboy4life]

Figured we needed one of these. The wiring is one of the main concerns people have about the swap. Of course if you don't feel like messing with it theres API, Chasebays, and Rywire whom you can send your harness's to and they can modify them to be plug and play.

I'll start it off with a '03 CL-S M/T ecu pinout attachment at the bottom.


EDIT: Rywire notified me that he has a CL and a odyssey harness and they don't match the pinout that i attached so use it as reference at your own risk :P Also i just added a '03 TL-S pinout attachment.

6/3/09 EDIT: here are the pinouts that are from the TL 99-03. They should be good to use as reference. Ryan said this is what he used.

[jdmjohn]

any info on the plug that has to be spliced into the civic/acura harness?

[Rywire]

Ya im doing my first harness right now, I have the pinouts, and ill let you guys know how many wires need to be tapped into the ecu plugs...

Basically the eng harness has all the ecu plugs, minus the A, so A needs to be wired into your old ecu plugs... depending on the ecu, you will need to tap 5-10 wires... Ill have more info soon

[Rywire]

So it looks like around 15 wires need to be tapped at the oem ecu plugs.... thats if you dont want codes. If you have an aem that can turn off things like purge, and you dont have pow. steering, bksw, immobilizer, exc... you can cut it down to just a few wires ;D

Wanna share that info with us by chance? ;)

[Rywire]

What do you need to know?

[jdmjohn]

can someone post the "how to" on the j harness to eg/dc harness.... what wires go where.. to get the tach, speed and so forth..

[KhanhCord]

hmm.. if thats not the right pinout, what's the right one...
where do people find pinouts anyway... is it in haynes? i need to go buy 1...

[hondaboy4life]

I have one that should be the right one. I will post it up either later tonight or tomorrow, sorry i'm super busy trying to get my other car running.

[Becoming]

For those that don't have their harness yet, they can be purchased new for around 270 from Acura, And the A plug needed can be sourced from any K series engine harness.

[hondaboy4life]

Are you sure the k series plug with work...? is it the same pinout etc?

99 TL pinouts added.

[Rywire]

It depends on the ecu... the cars that I am doing are both 00-03 ecu, and are not the K plug pinout... they are more like a 99-00 civic si
here is a jumper I made...
http://i70.photobucket.com/albums/i85/droppedcrxsi/DSC01394.jpg
What you are looking at is the 00-03 ecu in a eg... the shock tower jumper is coming soon, I dont need the 2nd o2 on this harness, but that can be added in a pigtail off it...

[Becoming]

The one I got from the un-used CRV harness plugs into the CL-S ECU, just gotta move 4 wires that are not in the right place on the CRV plug into the correct position in the plug that there were empty cavities, but it'll work. The jumper harness Ryan made will be the easiest and most logical way rather than sourcing one like did for most people{including myself} so I don't fk up the wiring ;)

[jdmjohn]

So how much is this nice little thing gonna run, and also can you tell how it works... do the stock EG ecu plugs plug into the conv. harness and then the 1 jumper plugs into the j ecu?

[Rywire]

Since the J dosent have the A plug on it... you just need to tie it into the interior plugs straight up, so this jumper will take care of some of the functions. Next, the eng harness needs a few wires from the shock tower, I was making a jumper from the j shocktower to the eg shocktower, It will be done soon, I had a setback (I need to get a K harness made for my buddy )

[6CYL-IN-TEG-RITY]

I guess I'm gonna be the first one to say it but thanks a lot you guys for sharing this info. I hope I can find helpful info too.

[Chase Bays]

Chase Bays is now providing J series engine harness modifications. Got everything figured out and ready for orders.

As usual we will still be doing our CM1, CM2, and CM Mil Spec for J series engines.

Once we finish up our current customer cars there will be pictures up of all our J series products, we also provide Clutch lines and Fuel line kits.

[the blurr]

what do you do if you have a manual swap j32a2 with a 03 accord trans and a auto j32a2 harness

rywire or chasebay how much is it for the harness modifications

[hondaboy4life]

a new MT CL-S engine harness is only like 250-300 from the dealer i think... May be easier for whoever is doing your harness but they would need to confirm that.

[Rywire]

So here is where I am now on the J stuff....
As you can see there is a Jumper for the ecu so its all plug and play... the eg shocktower plugs are pinned on, everything has a place

[junior78]

looks really good ryan good work... is this harness gonna be like the k harness it only comes out of the one side of the firewall

[Becoming]

Can you confirm that it works yet? If not, send it to me and I will let you know what happens ;)

[dseriesdrag]

Rywire:

Do you know which vehicles had the correct harness in them that you would need to modify? Like year, make, model, auto or manual??? Would I have to have the matching ecu?

[Rywire]

Its for an auto eng/ecu in a manual car, chipped to manual ecu... the o2 was just to cover my ass, I did another, no egr, no o2, no smog crap... just the basics

[dseriesdrag]

Where is Rywire???? I need some answers! j/k.

[skandal57]

I just got my ecu in the mail.. its a type s but from the automatic. it was only 15 dollars on ebay so it was worth the gamble. i have an auto engine and full harness anyways. i just got my transmission in the mail also.

[kulrevon]

cant you run the richiev6 module so you can run the auto or manual ecu?

[acidbath124]

if anybody is still having trouble with wiring call don at rpm systems he can make you a set of jumper harnesses thats pretty much plug and play. thats what i did and it works great and he does awesome work

[splat]

what is the "richiev6 module" ? the motor will start will start with a different ecu , but the lower cam gear have different teeth , plus pick-ups . then the motor goes into limp mode. so if there is some that does make a manual ecu work on a auto motor PLEASE tell me ?

Just to let you know....i am not richie, Don wanted to know who Richie V6 was and what type of harness he mad, so i put it up.

[Becoming]

And what is that gonna cost?

[hondaboy4life]

Richies box costs about $500.

[rafybuilt]

can some post more bout the shock tower wiring?? do i connect the engine harness to driver side plugs? im using a 03 tl harness into a 95 civic

[Richie V6]

Hey guys I just found this thread. Here is the new version of the 5AT to 6MT swap module I have added some revisions just for this swap I hope to test them soon.

Without you going into too much detail so you don't give away what you are doing with the ECUs, what is your system basically doing to run the auto engine/manual trans setup if you don't mind?

[Richie V6]

It basically give the ECU all the feedback it needs to run complaint free. It also does all the speedo and RPM corrections. So far everything seems to be running properly but we still need to do more testing.

[Lightweight]

Do you think that you guys could use a 04 accord harness?

[Richie V6]

your device fixes the tach and the speed offset? or does it make the check engine problems for the auto tranny go away?

don
rpm systems

Both.

Hey Don,
I read that you had a solution for replacing the immobilizer boards. How does that work and is it out yet?
-Rich

[jdelsol]

This box might be worth it because I will easily forget to subtract 8mph from the speedo at all times. Also to pass inspection.

[Hakd.Inc]

it works. its a pic chip . i have not had many people ask for the as there mod there own ecu and dont care about the codes.

How do most people mod there own ecu's to eliminate the immobilizer, i have heard that people just unsolder the immobilizer and say it works, but this is not verified, I don't care about a Cel code, that is the least of my worries, i dont have the keys to the ecu i currently have.

Also on another note is there any way that we can post up a conversion chart for what needs to be wired in. Like say it is Plug C on the accord, and plug A on the eg civic and what needs to be switched over, Or maybe some more pictures into this, I have a general idea of how to wire this, But i am making this a whole wire tuck, with no Wires visible at all and once i figure this out i will post up all the info that i have used, and pictures of my thread...

[hondaboy4life]

It is actually verified that removing the immobilizer works... theres threads about it floating around... as for wiring, if somebody figures everything out and wants to post it thats fine. I simply don't want to be the one to do it out of courtesy of the sites sponsors who sell conversion harness's.

I will tell you that i have a full wire tuck and am running rpm systems $300 conversion harness setup and it is working great ;)

[Hakd.Inc]

So just removing the immobilizer chip works then i am set.

Also with the wiring i am still skeptical on how to wire these, Does the full Tuck harness move the plugs on the drivers side where? just into the cabin? I understand what you are saying with the sites sponsors, but still how many people want to go hacking into there wiring, i know i am capable of doing this, but many others may be unwise to do this, I have been researching all the wiring i need to do, and am still lost, pretty much it is use the engine harness and splice the 10-15 wires from the stock harness to the J harness.... This would include items suck as Fuel pump, Vss, and gauges...

[hondaboy4life]

no splicing is really required. You can pretty much make it plug and play. You need some wires from one of the shock tower plugs on the j harness to your stock chassis side shock tower plugs and then near ur stock ecu plugs is where you can tap in for everything else.

[acidbath124]

talk to don at rpm systems he can make you a plug and play jumper harness to connect the C101 and C102 plugs to the strut tower plugs on the driver side and a seperate one to plug into the ecu

[TIFFSJ30]

yea but don just dont sell the harness for c101 an 102. i have called him none of his harness are 300 dollars. an if u build ur own jumper harness all the wire are pretty much the same color thats a good thing that honda did on the wiring.

This diagram is included twice in the OP it looks like. If you have the second sheet that'd be fantastic as I'm unsure what the other 13 pins lead out to. I'm in the process of tracing them, but it'd be awesome to just be able to cut a few.

;)

[RPM SYSTEMS]

i dont sell the small adapter harness anymore . due to people try to cut up there harness then blame me for the short comings. so i build a full harness that is plug and play so there are less problems with people. i still get the calls that the harness has a problem , but it is mostly from guys try to wire tuck the car . with the way i put the harness together it is plug and play . vechile speed and tach work , as will as the other sensor . i make the wiring from stand-alone race harness to 88-2001 honda/acura plug and play's .

to get back to the comment about sell just a part . ask yourself this , would you go to McDonald and as the server for a hamburger . but you brought you own meat to put in the bun. no you probably would not do that . so why should I .
