Truck wiring harness Q's... So I have a '04 5.3 with matching harness. I ahve the PCM mounted inside the car already. I have 4 tan wires taped together coming out of the pcm side of the harness I'm trying to splice into the car. Does anyone know what these are without me having to yank the harness/PCM out?
