Made that connection also at the rear camera power source in the rear and simply grounded the rear camera ground wire right at the rear fuse block mount.

My rear camera is powered whenever the Avin is powered up but mine needs to be that way so it records the rear along with the front as dash cam functionality. I really don't see a downside to having the camera ACC powered.

If you really only want the camera powered in reverse only, I would grab the 12V reverse signal from the LCM that goes to the autodim interior rear mirror. It is a solid 12V and not PWM power like the reverse lights.

One last note, there is no interference at all with my rear cam view.
