I've come across some wiring schematics and it looks like my gf's g6 does not have the accessory nor backup lamps cable.
Is it possible the additional wires are above the headliner? I took the dome lights off and couldn't really find the wiring for the mirror.
I'm hoping I can just order a replacement harness and the additional wires are in the headliner unused.
I'm hoping GM used the same wire bundle across all of their g6 line.
Onstar works though.
Any ideas how I can get accessory power to it?
