I have a 1990 crx with a z6 in it, but all the wiring is cut right where it comes out of the fire wall, and the body harness is gone, but I have a body harness and a used wire harness. But I was wondering if I could buy the plug and play from Rywire and hook it up because the used harness is a cluster fuck. I also do not know if I need to get the obd0 to obd1 jumper harness. It has a p28, and everything is on the motor, just no harnesses.
