I have two engine harnesses/ecu's. Both are from 89 turbos, one early 89, one late 89, one auto, one manual. MY car is a 5 speed, and i currently have the factory wiring/ecu in it. The wiring harness i got from the automatic car is in nicer shape, and i was wondering, can i run the auto harness in my 5-speed car without any modification? If so what modification is necessary? If i cant do this, could i run the auto ecu along with said wiring harness on my 5-speed car?
