back-up/rearview camera wiring not working
Our 2017 29HFS came pre-wired for a wireless back-up/rearview camera The bracket is mounted above the center running lights above the rear garage door.
When I plugged the camera in to the pre-wired connector, I don't get power. Tried it with running lights on, in reverse and with loading ramp lights (reverse lights) on. The paperwork that came with the camera says that FR wires the camera to the running light circuit.
Any ideas where a fuse might be in that wiring? Any ideas how to get to the wiring above the garage door: do I go through the ceiling or by removing lights on the exterior?
