In my swap I didnt use the Air conditioner or Power steering. The wiring for the alternator ( i believe ) was on the B12 harness and the one for the starter may have been from the B13 harness. I cant quite remember, it has been over two years.RockyB said:For the guys who did the sr20de or det conversion. How hard was it to wire the car? Was it just wiring for the ecu. Could you use stock wiring for the alternator and starter. Also, did you use the a/c and power steering, were they eliminated?
