Ok so I had a 90 crx dx and bought a z6 swap from a friend. I had a well known honda mechanic put it in, he done the mpfi conversion and obd1 conversion using Phearable jumper harness and ecu. Well it was running unbelievably great and then one day my front wheel came off as I was driving and I totaled the car. So I bought a 91 crx si from another friend. So my question is would be easier to use the converted harness or the factory si harness. I would think the converted one would be the easiest but I don't know what to do with the resistor box and its wiring. Someone please help me!!
