I dropped a zc dohc into my 90 rex and have terrible wiring problems. Its a dx and the wiring off the ecu looks like a birds nest. Does anyone have a wiring diagram for a pm6 as to what wires go where, or have a wiring harness to sell me? Any help would be appreciated. It constantly is poppin a code 3 and 13, and I replaced both of those sensors. When its not poppin those, its an O2 sensor code. Please help! Thanks!!
