Hey guys, I have a 2004 Cavalier Ecotec engine for my 1988 Pontiac Fiero. I have the guage pod from the original car, the engines wiring harness and ECM, but no BCM or wiring from that.
The wires that plug into the back of the gauge pod are what I am having trouble with. Does anyone have a wiring diagram of that circuit? Or even all the wiring diagrams for that car? It would greatly help me mesh my two wiring harness together so I can hav a functioning stock guage pod for now. Thanks a lot. Ciao
