i have a 1989 crx with a 93 integra swap in it. i have infinite issues with the wiring, i suspect this might be becuase the person who did the swap used an improper wiring harness for the swap. i have indentified the ecu in the car as a pr4 which would be the proper ecu. my quetion is... would it be possible for the original wiring harness from the crx to be plugged into the new integra ecu?

 

Is the crx DX, HF, or SI. The harness body harness will plug into the integra ecu.
