Before you begin the installation...
If the motorhome (or towing vehicle) has a separate
lighting system, a 3-to-2 converter must be installed in
order to use this kit. A 3-to-2 converter converts a separate
system to a combined system.
Many late-model motorhomes come with converters
already installed — test for this before installation: if
the motorhome's trailer plug energizes the same pins
for both brake lights and turn signals, then a 3-to-2
converter is already installed and the motorhome (or
towing vehicle) should be treated as combined.
If a converter is needed, install ROADMASTER's
Brite-Lite , part number 732.

Installing the lights...
If the towing vehicle is not equipped with a four-wire
electrical socket, first wire the included socket by following
steps 1 through 5 below. (If the towing vehicle already has
an electrical socket with a six- or seven-wire plug, it may be
more convenient to replace the existing six- or seven-wire
plug with the included four-wire plug.)
1. Choose a mounting point for the electrical socket — look

for an area at the back of the towing vehicle, which you
can easily reach and with a surface of sufficient strength
to hold the socket firmly in place. The mounting point must
be close to the center.
CAUTION
The socket must be attached at the rear of the tow-
ing vehicle, close to the center. Attaching the socket
toward either side of the towing vehicle may cause the
wiring to be pulled from the socket, or to drag on the
ground, when the towing vehicle turns.
2. With a Phillips screwdriver, remove the set screw
(Figure 2) from the back of the socket. Then remove the
plug from the socket housing.
3. Use a test light to identify the towing vehicle's left and
right turn signal, ground and taillight wires on the electrical
harness. Push those four wires through the back of the
socket housing.
4. Attach the wires to the back of the plug (Figure 3 shows
the attachment point for each wire; use the notch at the top
of the plug as a reference.)...
First, strip a small amount of insulation from the end
of each wire. Then unthread each connector screw on the
back of the plug, and insert the ends of the wires into the
appropriate wire cups. Tighten the connector screws to
secure the wires in place.
Unless each wire is attached to the correct wire cup,
as shown in Figure 3, the magnetic lights on the towed
vehicle will not illuminate in tandem with the towing
vehicle's lights. Drivers behind the towed vehicle will
not be alerted when the towing vehicle stops or turns,
which may cause an accident.
Failure to follow these instructions may cause prop-
erty damage, personal injury or even death.
