I have an 03 GTP i have a yellow wire going through the firewall that comes from the ecu in airbox. it broke off when i was installing sub wiring today and i have no idea where it goes inside vehile please helppp
Well the wire pulled through the firewall and broken not by the pcm. it is a single wire with its own wire loom. My buddy has an 01 GtP and his does not have this wire.?? Need a pic, cuz all the wires coming from the pcm are wrapped pretty well and are really tough to "break" just running the power wire.
