Thread: Rear view mirror wire/plug diagram pinout?

I am wanting to hook up my dashcam with as little wire routing as possible. I am wondering if I could use the wires going to the rear-view mirror as a power source because I am obviously not using onstar. Does anyone have a diagram showing the ones that supply power? I could use a 12volt or of I am lucky there is a 5 volt one up there like I have saw in other cars. that would be perfect because the cam will use a 5 volt USB plug for power.
the car is an 07 GXP

I have wiring diagram for 99-03 but would have to find it.

Let us know if you figured it out...

I wanted to avoid the main onstar wires because they tie into the PCM just to be safe I wanted to avoid those. My c5 Vette had a 5 volt wire in the mirror harness that I have no idea why. It did not have onstar I never did figure out what it was there for but i did use it to power a camera for years with no problems.
