Roadmaster Wiring Kits


By law, a towed vehicle’s turn signals, running lights and brake lights must mimic
the motorhome’s.

There are three ways to accomplish that:
1) a system of diodes;
2) installing new taillights in the towed vehicle; or
3) magnetic tow lights.

Each method has its advantages. Whichever one you choose, ROADMASTER has a kit with all the necessary components, and step-by-step instructions.


Three Wiring Methods


Universal Wiring Kit

This kit uses a system of diodes to connect your towed vehicle’s turn signals, running lights and brake signals to your motorhome’s. Diodes prevent electrical feedback and protect both vehicles’ electrical systems. The kit comes complete with: • four Hy-Power™ diodes (more diodes may be purchased separately); • a 30-foot strand of four-wire electrical cord; • three feet of split wire loom; • a six-foot extension cord (connects electricity between the two vehicles); • a ring terminal; • cable ties; • wire connectors; and • step-by-step installation instructions.

Taillight Wiring Kit

A self-contained wiring system that bypasses your towed vehicle’s lighting with a set of independent plugs and sockets mounted inside the taillights. Wiring is routed from the taillights to the grille area. Since the towed vehicle’s electrical system is bypassed, this kit eliminates the concern of voiding the vehicle manufacturer’s warranty.
Note: the towed vehicle’s taillights must have room for an extra socket and bulb inside the lens housing.
