Hello,

Does anyone know if I can tap into the wiring behind the rearview (OnStar) mirror to install a power cable for a radar detector?

If so do you know of a wiring diagram to indicate what colors the power and ground wires are?

Thank you,

Thank you,

I spent about an hour messing around with every wire combination and a voltmeter and i could not find a good switched 12v source near the mirror and ended up running it from the fusebox. :gfy:

Thanks, I will then run to the fuse box.

This is driving me crazy. Another GM car I have uses the pink wire for ignition and the black for ground on the mirror harness. The V1 works great. The cruze has the same pink wire in bank 2 (exiting white/violet) and the same black ground wire. I do not understand why this doesn't work?? I wonder if the larger inviscord pins are just too big for the bank and not making connection..
