Question:
We just purchased a 2020 GMC 3500 HD diesel Denali and find that when hooked to our DRV holiday trailer we have no lights or brakes The truck computer does not recognize the trailer says trailer not connected We believe it has something to do with the lamp out sensor on the truck and the LED lights on the trailer We are looking at your wiring adapters and see C57003 and 20142. Will one of these adapters work with our 2020 GMC Denali

Helpful Expert Reply:
Both of the parts you mentioned, the Trailer Connector Adapter with Lamp-Out Sensor Bypass # 20142 and 7-Way Trailer Adapter # C57003 are universal parts so both will work on your 2020 GMC Sierra 3500.
The Curt 7-way adapter is put in our fit guide as a wiring option for certain vehicles to help those customers find it but it is a universal part so it will fit on your Sierra.
I have added links to video reviews of both parts for you to check out.

Just purchased a 20142 adapter for my 2019 GMC Sierra, the Furrion FOSO5TADS. The camera has linked with monitor but still no backup view. Tried with different truck and camera works fine. Has there been any reports of faulty adapters?
