Our 2106 262rgx had a white plug covering a hole where the camera would go. Wiring was in that. I can't remember why, but when I installed a Furrion wireless camera, I could not use that wiring and just tapped into the running light just above it. So, the headlights or running lights have to be on for my camera work.
Now that I think about it, the wiring that was there may have been to connect it to the backup lights. I don't think I ever checked that because I wanted the camera to come on whenever I wanted it to, not just backing up.
If it's not wired for it, it is pretty easy to install a wireless if you just tap into your running light for power.
