2013 Voltage Backup Camera

I accessed mine (3200) through the light in the back above the bunk and split the power lead and wired in a switch I put on the wall to be able to turn the camera off. Turned out to be a mistake because the camera fogged up. The radio and tv area in the garage area would be the likely spot as it has a constant 12V source for the radio. Sliding out the radio exposes the mess of wiring the factory installed. There is also an access point in our back cabinet that exposes the wiring in the wall. Not sure where it is on a 3600. Hope this helps.
