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 the towed vehicle to the motorhome);
• 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 car’s turn signals,
running lights and brake
lights with a set of independent plugs and
sockets mounted inside the taillights. Wiring is routed underneath the car, to a
socket mounted to the grille
or fascia. 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.

Magnetic Tow Lights
ROADMASTER’s magnetic tow lights are the quick and easy way to connect your towed car’s electrical system to your motorhome’s. The system is self-contained, and requires
no splicing into the towed vehicle’s electrical system.
• Fits all vehicles
• Magnets hold lights securely
• Eliminates electrical damage
to the towed vehicle
• Heavy-duty vinyl casing for
maximum wire protection
• Meets DOT standards
• Includes plugs, sockets, and wire harness

Flexo-Coil™ and Straight Electrical Cords
Whatever electrical system you chose, you’ll need a cord to connect electricity between the towed vehicle and the motorhome. ROADMASTER’s are the best — the wires are water-, oil- and chemical-resistant, and the plugs are injected with silicone to prevent corrosion. ‘Flexo-Coil’ cords expand to over eight feet, and conveniently contract for storage; use a straight cord kit for ROADMASTER All Terrain tow bars.

Electrical Socket Brackets
These brackets hold the towed vehicle’s electrical socket firmly in place, making it easy to plug and unplug the electrical cord.
ROADMASTER’s socket brackets are made of 1/8-inch thick steel — not lightweight sheet metal. Both straight and angled brackets fit most electrical sockets, and can be either welded or bolted in place. Black powder coat finish.

Brake-Lite Relay Kits
Why do we manufacture Brake-Lite Relay kits?
By law, all towed vehicles must have brake lights and turn signals that illuminate in tandem with the motorhome's. No other supplemental braking system manufacturer provides this accessory. As a consequence, many of their customers end up with traffic tickets — or worse.
When do you need one?
If the towed vehicle's brake lights override the turn signals, you will need a Brake-Lite Relay Kit.

Park Light Diode
Problem: Electrical damage can occur to the towed vehicle if its headlights are turned on while still connected to the motorhome.
Solution: Use a Park Light Diode to stop any interaction between the two park light systems, preventing electrical feedback and electrical damage.

Brite-Lite™ Wiring Converter
If you have this — the motorhome has separate brake and turn signal lights; the towed car has combined brake and turn signal lights.
Then you need this — the Brite-Lite Wiring Converter delivers more current to the towed vehicle’s brake and turn signal lights for brighter illumination.
