You will not need the 7-Way Vehicle Power Adapter w/ Power Switch for Furrion RV Observation Camera
# FR69SR to hook up your camera system. This adapter was only designed for trucks from 2019 - 2020 because of those trucks not delivering enough power on the running lamp circuit for the camera system to operate fully.

I would suggest checking the fuses to make sure there are none that are blown. I would also re-check the wiring, especially the ground wires to make sure everything is connected as it should be. I've provided a diagram showing how a 7-way is pinned out. You'll need a circuit tester like # PTW2993 to test each pin as its function is operated.

If you let me know what camera system and trailer you have, I can help you troubleshoot the issue further.
