Our WJ came pre-wired for it. There is a pre-wired connector that the Furrion Camera plugs into for 12v power. The 12v Power comes from the TV parking lights (or running lights, what ever they are called). So to keep power to the "stock" setup, the TV parking lights or headlights must be on, day or night.
