There is a way you could wire a RoadMaster Tow Dolly with Electric Brakes, part # RM-2050-1, to allow you to use the tail light functions of the tow dolly and to activate the tail lights of your 2004 Chevy Colorado while being towed.

I spoke with my contact at RoadMaster and he informed me that there is not a kit or harness that you could buy that would allow you to do this, and that you would need a Roadmaster Universal Hy-Power Diode Wiring Kit, part # RM-154, and you would have to do a little fabricating to make this happen.

Basically what you would need to do is tap into the wiring harness of the tail lights on the tow dolly and then use the # RM-154 to take that signal to the tail lights of your Colorado. I attached a video below that shows how the # RM-154 installs into a vehicle to show you what its like. I also attached an FAQ page on diode kits below also.

For tapping into the tail light circuits I would recommend using quick splice Connectors - Blue Gel, part # SWC501746-1. I attached a link to a demonstration video for this product below. For testing the wires to determine what wire should be tapped into I would recommend you use a circuit tester, part # PTW2993.

Or if you wanted to simplify the installation you could use Magnetic Mount Stop, Turn and Tail Towing Light Kit w 20 foot Wiring Harness, part # TL21RK. This kit would magnetically attach to your Colorado and provide turn and brake signals without having to wire into your Colorado tail light circuitry. You could use a
4-Pole 60 inch Long Vehicle End, part # 18002, to tap into the brake light circuitry of the tow dolly and then run it to the # TL21RK to provide the tail light functions.
