WIRING
Note: Some towing vehicles may already have a 4-way Flat Connector, “Trunk” plug
wired in. For those vehicles, skip the following wiring instructions.
If you do not have experience
doing this type of automotive
electrical wiring or if the
wiring in your vehicle differs
from that explained below,
have an automotive service
technician connect the wiring.
Identify the towing vehicle’s wires1.
in the trunk that correspond to
the circuits indicated in the Wiring
Color Code diagram to the right.
The white ground wire from the
Pigtail (22) may be connected to a
bolt or appropriate component on
the vehicle to establish a ground
instead of a ground wire.
2. Connect the wires from the Wiring Pigtail (22) to the proper vehicle circuit wires
using Wire Splices (21). When the supplied splices are used, generally no wire
stripping or cutting would be
required. Follow these three steps
and refer to the illustration to the
right:
Insert the end of the Pigtail (22)a.
wire into the ‘dead-end’ channel
of the Splice. Insert the wire
all the way to the end of the
channel as shown.
Place the Splice around theb.
correct vehicle circuit wire.
Make sure both wires stayc.
properly in place while the
cover is closed until it snaps
together.
Wiring Color Code
Note: This is the wiring conguration of the
“Trunk” 4-way Flat Connector (23). The
towing vehicle may have a different wir-
ing color code.

Verify that all wires are held securely.3.
Plug the “Trunk” Connector (23) into the “Trailer” Connector (18).4.
5. WARNING! If the Wire Splices (21) are used improperly and damage
the vehicle’s wiring, the vehicles rear lights may fail, resulting in a trafc
hazard. Have an assistant operate the vehicle’s lights while you carefully
check that the vehicle lights and the towing lights all work properly after
installation. If any function of the vehicle or towing lights does not work, do
not drive the vehicle. Carefully inspect the splice connection and the circuit that
failed and repair the problem and retest before use.
Disconnect the “Trailer” Connector (18) if the light kit is not going to be used yet.6.
SET UP
To help avoid scratches, clean the mounting locations and clean the protective1.
labels under the lights.
Set the lights on the back of the vehicle being towed so that the2. RED side of
each light faces backwards. Set the light that has a green wire on the right side
and the light that does not have a green wire on the left side.
Make sure all wires are secured with enough slack to prevent binding when3.
turning, but controlled enough to prevent roadway or moving part contact.
When routing the wires along the trailer, avoid sharp objects, tight corners and
exposure to the elements. Keep away from moving parts. Secure with cable
ties where necessary and use rubber grommets when passing through cut-outs.
Plug the “Trunk” Connector into the “Trailer” Connector.4.
5. WARNING! Have an assistant operate the vehicle’s lights while you
carefully check that the vehicle lights and the towing lights all work
properly.
Both tow lights should illuminate when the towing vehicle’s running lights are•
switched on.
The tow lights should both light brightly as you apply the brake.•
The tow light with a green wire should blink brightly with the right turn signal.•
The tow light without a green wire should blink brightly with the left turn signal.•
If ANY function of the vehicle lights or towing lights does not work, do
not drive the towing vehicle until all lights are repaired and retested
successfully.
The tow light kit is now ready for use. It will automatically illuminate when turn6.
and brake pedal or turn signals in the towing vehicle are used.
7. WARNING! Check light position and function regularly when towing,
especially on rough or uneven surfaces. The magnets cannot hold the lights
to the vehicle in extreme circumstances.

included) to prevent damage.
Press the burned-out bulb into the socket slightly and rotate it counterclockwise3.
to release it. Make a note of the orientation of the pin’s as one is located lower
than the others. Remove the burned-out bulb.
Insert a new 12V/21/5W bulb into the socket (note pin orientations) and while4.
pushing it down turn it clockwise to secure.
Gently snap the lens back in place, and test the lights to ensure proper opera-5.
