Selectingtheelectricalwiringcomponents
By law, it is necessary to have a lighting system in the towed vehicle that will allow the towed
vehicle’s brake lights, turn signals and running lights to mimic the motorhome’s. There are three ways
to accomplish that:
• UniversalWiringKit — the most popular method. Connects the towed vehicle’s lights to the
motorhome’s with a system of diodes.
• TaillightWiringKit — a self-contained system,
with no splicing into existing wiring. Bypasses
the towed vehicle’s lighting system with a set
of independent plugs and sockets mounted
inside each lens housing. (The towed
vehicle’s lens housing must have room
for an extra socket and bulb.)
• Magnetic Tow Lights — a self-contained system,
with no splicing into existing wiring. Fits all vehicles.
In addition to one of the three wiring methods above, a power cord is required, to connect the
two vehicles’ lighting systems.
• Flexo-Coil™ or straight?
• Flexo-Coilpowercords are used with tow bars without a channel guide (Falcon 2,
StowMaster, Tracker).
• Straight power cords are used with tow bars with a channel guide (All-Terrain tow bars).
• An electrical socket bracket is used to mount the socket to the front of the towed vehicle.
Selectingsafetycables
and electrical wiring
coiled safety cable
straight safety cable
One of the first determinations is the type of wiring. There are three:
• 4-wire — a four-wire component fits towed vehicles with combined brake and turn signals — that
is, the brake light also does the flashing for the turn signal.
• 6-wire — a 6-wire component fits towed vehicles with separate brake and turn signals (there are
amber or red turn signal lights, which are separate from the brake lights.
• 7-wire — a 7-wire component is primarily designed for towing a trailer. However, many newer
motorhomes have 7-wire electrical systems.
Selectingsafetycables
Safety cables are an integral part of the towing system. They are a
secondary safety device, required by law in many states.
Our aircraft-type, galvanized steel safety cables are continuously tested
to ROADMASTER’s relentless standards.
• Matchthevehicle’sweighttothesafetycable.
• 6,000-pound capacity cables are available in either straight or coiled styles
• 8,000-pound capacity cables are available in straight style
• 10,000-pound capacity cables are available in coiled style
• Safetycableextensions
• Required for use with hitch extensions, high-low
receivers, or any accessory which extends the length
of the towing system
• EZHooksafetycables
• Quicker and easier to connect and disconnect
• 6,000-pound capacity
• Come standard with the Sterling All-Terrain tow bar
