im about to pull out my d16y7. everything is ready to go... until my buddy noticed the wiring harness that goes into the firewall for the ecu doesnt have any plugs. its all one peice... the harness runs straight to the motor.

now my gsr motor has the wiring harness already on the motor but it has the plugs. so im missing the part that comes out the ecu into the engine bay. its hard to explain i really need picture i know but my computer has so many stds (virus) it takes forever.

if anyone can help me out id appreciate it. thanks

you need to use the search button, but your gonna have to modify the ek harness cause the integra harness wont work with ek's

integra engine harness are a 2 piece design while 96-00civics are 1 piece design

HarosGSRek

well that makes perfect sense. do you guys know where i can find one?

HarosGSRek

or is there an easier solution to this problem?

easier solution is use your stock d series engine harness

rick_rabies

ekb16 are you saying the D harness will work perfect minus the butterflys in the mani which he can just wire up?

HarosGSRek

if the d harness works ill take it off and throw it on the gsr like you said rick rabies.

dumpsterbaby

shame on you for not researching beforehand, good thing you got the integra harness so you can just take what you need off of it. also wat year is the integra motor? and wat year is your car?

rick_rabies

ob2a and obd2a 98 civic 98 gsr. i heard the D mounts work for a B swap in an ek is this true?

believe it or not a d series engine harness will plug up to a b series..its like WOW and all you need to do is add a few plugs/wires for sensors that you dont have on that harness like IABs, vtec, ks, 3wire IACV to 2wire IACV

rick_rabies

it seems as though you had to do something similar. is this what you did, if not what did you do. what is the simplest way to solve this. we have junk yards around us but no tegs, jus alot of civics.

i pulled my car into my garage to do a mini me swap and ended up doing this... its my first swap so im new to all this... im not sure exactly what year the gsr is from im guessing 97 or 98.

rick_rabies

its obd2a.which is 96-98 obd2b has different plug. and the p72 ecu u hav is def obd2a

OP if you still need help with this PM me. I just did one with a DX harness. Not hard at all.

reuse your stock D-series civic harness, add the vtec wiring and IABs, pinouts shown below. If that GS-R harness you have is USDM I wouldn't start hacking it up for plugs, they aren't exactly easy to find and there is a high demand for them. A better idea would be to sell the GS-R harness in the H-T marketplace and go to a junkyard and cut the connectors you need from a CX/DX harness.

1996 - 1998 Civic, use this pinout:



1999 - 2000 Civic use this pinout:

if this is your first honda swap, have someone help you who has done it already.. your best bet is to buy a 99-00 si harness that has ALL the plugs right there, the only difference is that you'll be obd2b ECU plug side. so instead of obd2a conversion harness for ecu u need obd2b.

R666_EK

Why the hell would you use an SI harness? The EX harness will be the same thing only obd2a which will be much much better for him. The swap is not hard at all. I did my first one 99% by myself. You'll be fine. The wiring is the only thing that is somewhat a challenge. If you don't want to re wire the DX harness then pick up an EX harness and call it a day.
