So converting a ef hatch from auto to mania and swapping in a b20v from another ef hatch. Will be using a chipped p28 ecu. The harness from the car I pulled the motor out of is... rigged and bare wires, random wires cut and left open, and random wires add so I don’t want to use this wire because of fire hazard and the harness will corrode and cause issues eventually. I’ve been looking and haven’t found a decent obd1 swap for this. I’m super new to the ef chassi and found out I have to use jumpers and rewire and flip pins. I’m looking for a how to or a good wiring diagram for what I need to do. I’ll be able to take the plugs off the junk harness.

thanks in advance.
