TOOLS REQUIRED:
Drill (3/32" Drill Bit), Philips Head Screwdriver,
Wire Crimpers, Wire Cutters, Test-probe,
Socket or Wrench
NOTE
Some kits will require a wiring kit for installation
that may be sold separately.
1. Determine a suitable location for mounting the
circuit protected convertor in an out of the way
spot near the left tail light in the trunk or on the
frame rail, if mounted under the vehicle.
CAUTION
When mounting under the vehicle, always make sure
that the unit is in a protected area and can not be
damaged from road debris or objects driven over.
2. Locate a suitable grounding point near the convertor
such as an existing ground stud or drill a 3/32" hole
and secure the white wire using the eyelet and
screw provided. (Do not drill into vehicle floor
or bed.) Clean dirt and rustproofing from area.
CAUTION
Verify what is behind any surface prior to drilling to
avoid damage to the vehicle and/or personal injury.
Do not drill into any exposed surfaces.
3. Disconnect and isolate the vehicle's negative (-)
battery terminal.
CAUTION
Read and follow all warnings and cautions printed
on the tow vehicle's battery.
4. Using an in-line fuse holder, crimp a ring
terminal to one end (3/8" for top terminal or
1/2" for side terminal).
5. Attach the fuse holder (with fuse removed)
to the positive (+) terminal of the battery.
6. Route 12 gauge (or larger gauge) wire from the
fuse holder to the convertor passing under or
through the vehicle.
NOTE
When passing wire through sheet metal always go
through an existing grommet, add a grommet or use
silicone rubber to insulate the wire from the hole.
7. Attach the 12 ga. wire to the fuse holder and
07/17/08
convertor with butt connectors as shown in
the figure.
8. Reconnect the tow vehicle's (-) negative battery cable.
CAUTION
See tow vehicle's owners manual for
any special battery reconnection instructions.
9. Determine if the tow vehicle has a 2 wire or
3 wire system.
2 WIRE SYSTEM
a) Same bulb for stop and turn signals.
b) Some vehicles have a separate bulb for stoplights
but also have a combination bulb for turn and
stop (such as 2008 Ford Taurus sedans). These
cars should be wired as 2 wire systems, using
the wires going to the common bulbs.
c) Attach the crimp on spade terminal provided to
the red "stop" wire and ground it along with the
white wire (Mounting step 2).
3 WIRE SYSTEM
a) Amber turn signals.
b) Separate bulbs for stop and turn signals
(both red).
c) Some vehicles combine stop and tail light
functions onto 1 circuit (such as Mercedes
R-class). These vehicles will require that you
attach the trailer light power module red "stop"
wire to that same circuit on the vehicle and
then ground the brown "tail light" circuit.
d) Some vehicles combine stop and tail light
functions onto 1 circuit and then also have
an additional tail light function wire that is
independent of the stop (such as the BMW X5).
These vehicles will require that you attach the
trailer light power module red "stop" wire to
the same combined circuit on the vehicle and
then attach the brown "tail light" circuit to the
independent circuit on the vehicle.

10. Using a circuit tester, determine which wire
attached to the left taillight assembly is the left turn
wire. Attach the units yellow "left turn" wire to this
wire using wire taps. Determine which wire is the
taillight circuit and attach the module's brown
"tail/license" wire to it with a wire tap. Determine
which wire is the stop circuit and attach the
module's red "stop" wire to it with a wire tap
(for 3 wire systems only see step 9).
11. Route the units green "right/turn" wire to the
right side of the vehicle. Determine which wire
is the right turn circuit and attach the green
wire to it with a wire tap.
12. Install the 15-amp fuse into fuse holder and
test the installation with a circuit light or trailer.
TESTING PROCEDURE
With the ground wire connected and all of the
other circuits attached, attach the ground lead
of a circuit tester to the exposed ground terminal
of the 4-flat end. Activate the tow vehicle's left turn,
right turn, tail and stop lights one at a time. Probe
the three receptacles of the 4-flat end to confirm
proper functions.
If testing with a trailer, make the proper
connections and do the same test as the circuit
tester using the trailer lights. If a function on the
trailer lights does not work properly, disconnect
the trailer lights, turn functions on vehicle off and
recheck function with the unit with a circuit tester.
Then check the trailer for potential circuit problems.
13. Secure all loose wiring with cable ties.
WARNING
Overloading circuit can cause fires. DO NOT exceed
lower of towing manufacturer rating or:
• Max. stop/turn light: 2 per side (4.2 amps)
• Max. tail lights: (7.5 amps)
Read vehicle's owners manual & instruction sheet
for additional information.
