I have a b16a2 swap in my 1993 civic ex coupe. I am using a 1997 gs-r harness on the engine, because it plugs into the chassis harness. My problem right now is I am throwing like 5 codes. I believe this is occuring because I am using the gs-r engine harness instead of the Si one. But the Si one did not line up with the chassis plugs on the car side. I have a feeling this is causing most of my problems, does anyone know if it possible to rewire this harness and make it work an p30 obd1 ecu ? I hope so....Else, does anyone have a better suggestion? Let me know.

Someone suggested that I buy a 93 ex stock harness, and use that along with an OBD1 distributor. I think that will work ? Anyone know if that harness will line up better, and work better ?

I used an ITR harness on a B16A2 (USDM Civic Si) in my del Sol for the same reason. Worked fine once I figured out the IAT sensor was in the intake tube!

What codes are you throwing. Without those, you can't expect much help.

it wont have the knock sensor wire and you'll have to mod it a little to make it all fit.
