How’s it going, thanks for looking, I’m having a hard time finding any information on what I’m trying to do, I got an 86’ mustang I’m putting a newer engine in with stand alone harness and ecu, I plan on running a switch panel, the issue I’m having is the original harness is all one piece, as you guys may know, the engine harness is the headlight harness and windshield wiper fluid horns vacuum cruise control ect, then it plugs into the ecu very strange to me, this is my first carbureted car, so now I’m trying to figure out could I run through the harness and remove what I don’t need, including the ecu, so I can at least have all the headlights turn signals ac windshield wipers ect, and then I can place my new ecu for my newer engine in the place of where the old ecu was? I’d appreciate any wisdom!
