OEM Backup camera How-To: change to always ON
#11
I figured it out!
I also have the in-mirror display w/out onstarcontrols(I have onstar just no mirror controls) & no-nav, cut green wire pin 9 on mirror wiring harness, wire 12v with switch to pin 9, flip swith to power on reverse camera & display. Works like a charm. For safety I would suggest using a diode and an in-line fuse.

Why?
Well in my 2015 silverado I keep a gang box in back and can't utilize rear view, in my 2016 Gmc van I don't have windows so the camera would be very useful. Now that you have the way can you tell me how to do it? Or did you just want to comment?

Any update its been years?

We are missing some piece of info to get this working completely. Im sure something else needs to have power for this to work completely. If i get some time im planning on taking the rear panel off to check the voltage on the camera Form what i can tell it always has power but if Pin 9 is a signal for the BCM to power a relay at the camera i can see why the circuit times out after a few minutes.
Dose anyone have the Pin out for 07-14 mirror or better yet the whole circuit camera to mirror?
Every other forum out there has some special person stating why it should not be done. keep those comments to yourself. Lets keep this topic constructive and informative.
