Best Flat-Tow Wiring Harness for a 2021 Chevrolet Silverado 1500  


looking to flat tow my 2021 Chevrolet 1500 RST behind motorhome. What lighting kit do I need for tail,brake, turn signals etc


Helpful Expert Reply:

The best flat-tow wiring harness we recommend for a 2021 Chevrolet Silverado 1500 is the Roadmaster 4-Diode Universal Wiring Kit, part # RM-152-98146-7 for tow bars with wire guide channels or part # RM-15267 for tow bars without wire guide channels. These kits both provide all the required lighting functions (stop, turn, tail) to remain legal and they use the factory tail lights for a seamless look. They come with everything from the vehicle wiring to the umbilical that connects the vehicle and motorhome.
