Need Help with wiring harness. I have a 87 n/a and bought a 90 turbo japan motor and wireharness, ecu. I have everthing done but the wireharness. Is a Japan harness and U.S. harness different? What do I need to do to conect the wires together and make my car run.

 

You're in for a heap of work, lol. The entire dash harness has to be changed out, not just the engine harness and ECU since you're going from Series 4 to Series 5. Lottttssss of work from what I hear.

 

Hey,

Yeah White Seven is exactly right you got some work in front of you but in the end its all worth it, boost is awsome.

Cheers
Chris

 

I trying to splice the wires and match them up insyead of changing both wiring harnesses

 

I smell burning wires.



Don't **** with the harness. Just do the switching you can't splice into an N/a harness for a TII they are different harnesses and ECU's so wire probably don't go to the same places. Save the trouble of doing that and accoplish your swap the proper way.
