Installation
1. Starting in the engine compartment of the towed
vehicle, run the 26 ft. harness through the re
wall, under the driver's side door sill plate, under
the back seat, into the trunk area or run harness
through engine compartment and beside frame
rail to the back of vehicle. Depending on the
motorhome set up, the wire at the front of the
engine compartment should be wired into either a
4 or 6 pin connector that is mounted to the front of
the towed vehicle.
2. The bulb and sockets are installed into the
backside of the vehicles tail light assemblies.
The location should be as at as possible, with
enough clearance for the bulb on the inside and
the socket on the back side. Use a 9/16" drill bit
to drill a hole into each housing at the selected
location.
3. The black/red wire is the brake/ turn signal wire
and the brown/white is the tail light wire. The
white/green wire is used for the ground wire.
4. Insert the bulb and socket into the holes by gently
pushing them into place.
5. Run the black/red and brown/white wires from the
passenger's side socket to the drivers side where
the four wire loom is.
6. Crimp the three brown/white wires together. Now
crimp the green turn signal/brake wire from the
four wire loom, the green wire and the black/red
(brake/turn signal) wire from the passenger's side
together. The white/green (ground) wires should
be grounded to the frame with ring terminals and
self tapping screws. The white wire from the four
wire loom should be connected with the white/
green wire from the driver's side socket then
grounded. Refer to Figure 1.
7. At the driver's side socket connect the black/red
(brake/turn signal) wire and the yellow (brake/turn
signal) wire from the four wire loom. See Figure
1.
8. Place the wires out of the way. Test the system
before attaching the tail light assemblies back onto
the vehicle. To test the system, a 4-wire or 6-wire
trailer plug must be installed on the front of the
towed vehicle using the 4-wire harness installed.
Once installed, plug the vehicles together with
coach and test each turn signal and the brake
lights. If lights do not work properly, there must
be a loose connection, or a wiring error. Recheck
to insure all connections were made correctly,
especially the ground connections. The LED bulbs
are polarity sensitive, ensure they are installed
correctly. After testing, seal the socket to tail light
housing with a good silicone caulk and reinstall
the tail light assemblies.
NOTE: If the towing vehicle is equipped with separate
amber turn signals and red brake lights, a tail light
converter (not included in wiring kit) is needed
to convert the amber/red 5-wire system to the
standard “red only” 4-wire system.
NOTE: A heavy duty asher unit may be required in
the towing vehicle to power the added circuit load
of a towed vehicle.
