Yeah I'm not sure man. It'll be awhile before I pull the engine bay. When I do, I'm going to keep it all together so I can sell to someone looking for one. Have you tried Youtube?I have a 96 and have a cut in the harness and I decided if I'm going to put another harness in then put a 4 wire )2 sensor in. thats why I was wondering the plugs for the ECU because there are 2 or 3 different ones.
