I'm looking for guidance on installing an aftermarket rear camera. My main question is what is the best way to run wiring from back to front, which panels are difficult and what to look out for. I am also replacing the head unit stereo with an after market Kenwood and using the maestro RR and harness. So my question on hooking up the camera to the stereo is do I have to run a "trigger" wire back to the backup light or does the maestro/uconnect/canbus tell the head unit when the car is shifted into reverse. 2016 Renegade Sport Base Package, Uconnect 3.0. Thanks.
