We are trying to pair a Furrion observation camera installed on our SportTrek Touring 302VRB. Tow vehicle is a 2018 GMC Sierra with Advanced Trailering Package. This package uses PWM to power the clearance lights and the camera. Result is low voltage to the camera rendering it useless.
Furrion tech support recommend a “lamp out” adapter be purchased from etrailer.com. This also did not work. Called them back and they state only solution was to rewire the “pre-installed” camera connection directly to the 12V battery.
We we are looking for suggestion/instructions how to do this ourselves.

12V is 12V so a tap to the charging circuit in the 7 way plug would give you power when the trucks running.
So how did you post as a guest? I thought you had to be signed in to post anything.

Do you have the running lights on in the truck and camper? I've seen a lot of cameras power tied into the running lights.

You could always fish around behind the coach taillights to (maybe) find the feed that goes up to the clearance lights, then add a relay so they receive a true 12V from the battery up front. Of course this will require a wire being ran from the front battery. The other question is would the power (PWM) from the tow vehicle actually be able to run the relay. I don't understand why GMC is using PWM power for clearance /tail lights, not everyone has LED lights on their trailer, so really, a good 12 load such as a couple of standard bulbs should cause the PWM circuit to deliver more current. Here is a simple sketch of the relay method, assuming the tow vehicle clearance /tail light circuit would activate the relay.  |

Just a thought... the camera will only work if the headlights are on. You may already know this but just trying to think of reasons why you can't make it work.
