I just received this email from Furrion today. Apparently they now have an updated adapter for the 2021 models (Silverado, etc.). I already installed a relay to get the results I needed (and I'm happy with) so I won't be ordering one. Just an FYI for those interested.

So...I got tired of waiting for Furrion to come out with a suitable adapter that will work with my 2021 Silverado 2500 and wired in a relay to control the power to the rear and side cameras from the battery to bypass the PWM funkiness that's keeping me from running them. I'm sure Furrion will work something out but we have a big trip coming up soon and decided to bite the bullet and make this modification instead (plus I couldn't stand watching $700 worth of cameras sitting on my work bench). The mod was pretty straight forward and not technically hard, just time consuming. Underneath where the trailer/truck 7 pin connector goes into a small junction box you can separate out the connections to the running lights that are normally powered by the truck through the green wire. I have a 2021 GD Imagine 2500RL but this should be pretty standard on most TT's. I had three separate wires going from the Main 7 pin (Green) to the TT. One went to the rear tail/stop lights (for running lights) and also two lower marker lights together. A second green wire went to the Upper Rear running lights and the Furrion camera housing and the third green wire went to the Front/Side marker lights. Because my truck monitors the TT light connections I left the one green wire that connects to the Rear/Stop/Running lights connected to the main 7 pin connection. This way my truck will always see them and monitor the connection (otherwise I would have a constant fault/warning from the truck. These lights will be activated by the trucks headlights like normal. The other two connections I wired to a 12V relay. This relay is activated manually from a ground triggered switch I installed in the passthrough storage area. The relay is mounted underneath near the junction box. I've never installed/wired a relay before but it was pretty straight forward. Running the wire for the switch was also pretty easy because the wiring from the main 7 pin connector come up behind the wet bay panel. Just had to fish the wire through but was pretty simple. After all the wiring was completed and tested I installed the rear back up camera and it connected to the wireless monitor right way with no issues, strong signal and clear picture. Tomorrow I'll get the side cameras installed. The only down side to this set up is that I have to manually turn on/off the camera/marker light circuit. Not a big deal really. You'll know if you've left them on 'cuz all your markers light will be on. Technically you could also monitor the cameras from inside the TT when camping but again, your marker lights will be on at the same time. Anyway, just thought I'd share my experience with anyone who might be in the same boat as I was with the PWM system keeping you from running your cameras. If you have any questions please feel free to contact me.

I bought one of those but haven't installed it yet. Just curious, does your 3500 have the Advanced Trailering System (U1D) option? Glad to hear you got yours to work.

Thanks Daryl!

According to Furrion support, the problem I'm having is specific to the newer 2021 Silverado 2500 (and likely other similar GM models) and their current adapter won't work for me. Apparently there was a change made on the GM side for newer models. That is why they are working on developing a new adapter specifically for newer models. Apparently a lot of prospective Furrion camera users are having the same issue due to the new PWM systems. They also told me that the ASA adapter won't work in my case. Incidentally I recently asked Furrion for an update on the new adapter and received a reply this morning (see attached). Until they have a new adapter ready the only other option is to separate the running/marker light circuit (which also powers the cameras) and run them directly from the battery using an independent fused line with its own relay. It will likely also need to be independently switched because I'm not sure that the PWM voltage from the 7-pin truck/trailer connection with keep the relay latched (that's only my assumption based on what I've researched/read). It's a pretty basic circuit, just requires getting up under the TT, separating out the appropriate circuits and adding the necessary wiring, relay and likely a switch. Down side is I will have to turn on the marker lights (and cameras running off those circuits) manually from wherever I mount the switch on the TT (and remember to turn them off when stored). Not a big deal but not optimal. I'm not sure what functionality I might lose with the truck besides the light check feature (never use it anyway). I'm hoping that the side and rear marker lights (the circuits that power the cameras) are separate from the running lights in the brake/turn signal lights. If they are then I can separate only the marker light circuits I need (side and rear upper markers) and leave the running lights in the brake/turn signal lights hooked up to the 7-pin truck/trailer connection. This way the Truck will still see this load and not think there is something disconnected (if that's even an issue). I'm guessing the new adapter will be plug and play like the current ones and maintain full functionality between the truck and trailer. I'm also guess it will be around the $80-$100 mark (on top of what I've already spent on the 3 camera system with 7 inch monitor). Separating the circuits would be considerably cheaper I'm guessing. I think for now I might just crawl under the TT and investigate how I might/could separate the circuits and how much hassle it might be just to have an idea and wait another few weeks to see if Furrion comes out with something in the mean time. To answer your other question, I don't know if this is specific to the Advanced Trailering Package or not (I never asked Furrion) but it is an interesting question. all I can say is that I have the ATP on my Silverado.

Hi d61mccarty, I've been toying with the idea of doing the same thing. I have a 2021 Silverado 2500 and 2021 Grand Design Imagine trailer and have the same problem after spending $800 on the Furrion 3 camera system. Can you share a little more details about how you did this? What kind of relay did you use and how did you wire it? Thanks!
