'21 GMC Denali 2500 problems connecting to Furrion back up camera

[Katy44]

Part number for diode is incorrect in original post. It should be 621-SB550-T, not 651.......

I know this reply is a few months old, but I just traded up to a 2022 Silverado with the PMW problem. Question, Why the capacitor and diode? Would connecting the green wire supplying the front trailer lights work. #3 from the tow vehicle and #4 to the front lights. Would this activate the relay? I found the relay on Amazon and the capacitor, but having trouble finding your part number diode.
Thanks.

. The capacitor and diode are needed to keep the PWC happy And not having to flip a manual switch. There are probably simpler ways to activate camera, but this solution is hands off.

The diode number in original quote is inacurate. Should be 621-SB550-T, not 651.... Apologize..

Having this issue on my 2024 Silverado HD. They haven't fixed this, even with the new electrical architecture in the '24s.

I have the Furrion pigtail/7way extension, but that throws an error on my truck to "check trailer lamps" because it doesn't see a load on the green PWM line.

I have Haloview cameras on the two front side markers and the rear, three total.

I plan to wire the lights that also supply the Haloviews to the 12v charge wire coming from the 7 way, and leave those without cameras on the normal circuit. The cameras and lights will only power up when connected to the truck. I have a diode in place between the truck and trailer so the trailer can't push any 12v back to the truck on the charge circuit. This is to fix the other problem with the 2024 GMs where the brakes on the trailer are disabled if you have a solar panel... idiotic design...
