Question:

Do you have a “wiring harness” for a 2021 Chevrolet Silverado 1500 Trail Boss Custom I plan on “flat towing”.?I use a Demco Commander Tow Bar and Demco Base Plate. Thanks

I recommend using the Roadmaster Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267, which comes with diodes to prevent backfeed and gives you a great solution to power the lights on your 2021 Chevy Silverado 1500 when towing behind your RV. You may also need the Roadmaster Brake Light Relay Kit # RM-88400 if you're using this in conjunction with a supplemental braking system.

I've linked an installation video of this harness you can check out and use as a guide when it comes time to install this part.
