K I've got a obd2 integra with an obd1 ecu with a jumper harness. I'm throwing a tdc and ckp codes the previous owner did some wiring to the ecu for whatever reason, but anyways those wires are the thick ones with the bare wire wrapped around the inside of it . The main wires are in the correct pin spots but the bare wire that's wrapped around it is wired into the logic grounds (brn/blk) that are on the other connections ia that normal I really need to figure this out!
