Okay, so I am new to the whole wiring thing. Dropping a engine, no problem, wiring is. My boy who usually helps and knows wiring is in the reserves and was sent to Iraq. So he is not going to be of any help. So here is my problem. I picked up a 89 CRX HF, my first CRX, and have a '95 JDM B18C1 (OBDI), the ECU is a P73(OBDII). I have the HF completly gutted. I will only use the HF at the track and I wanted to know if it is going to make a difference with the wiring. Meaning: is there really a need for me to convert everything or can I transplant an Integra's wiring into the CRX?
