Has anyone got the wiring diagram for the alternator and battery and/or main engine wiring.
What model and engine?
I have the VT series 1 diagrams for V6 Ecotec, V6 Supercharged or V8 (5L). I don't have VTII or VX but i would assume the V6 models are similar.
Check out my post #6 in this thread it might help.
VT V6 PCM Pin/Wire diagram
If you want any of these PM me your email address and i'll send it you (N.B. these diagrams are too small to read due to this forum's "attachment file size" limits).
PM sent cheers mate.
