Ecu and wiring harness question. Please Help!!

Stainbox12 · 08-16-2007, 11:44 PM

I recently recieved by mistake a 91 harness, but my car is a 90. My harness is all messed up, and i already have a 91 coil, a 91 ISC, and i just ordered a 91 cas and a 91 power transistor, because i dont feel like cutting the good looking engine harness. However im planning on using the 90 ECU. Is it possible? ive seen people using 90 harnesses with 91 ignition stuff, but not 91 harness with a 90 ECU. Would i just need to swap the 2 wires on the Ecu Wiring harness and plug then the 91 harness to the 90 ecu and it will work or not? Im also swapping the tach to a 91 since the 90 works way different. Let me know what you guys think.

Lets see, 91 Coil, 91 PTM, 91 ISC, 91 gauge cluster, you need a 91 TPS and it will look pretty much like a 91 to the ECU so just swapping 6 and 14 should take care of the pin difference,
