Step 1
Open the tailgate and remove the vehicle taillight
assemblies by removing the screws and carefully
prying the taillight away from the vehicle (A).
CAUTION: Pry the taillights at
the indicated points to avoid damage.
Step 2
Remove the fasteners securing the rear scuff panel. Remove
the scuff panel by pulling out on the bottom and then up (B).
Take care not to damage the alignment tabs on the back.
Step 3
Remove the trim panel to locate the vehicle taillight wiring
harness connectors (C,D). The connectors will be similar to
those on the custom wiring harness. Separate the connectors
from the taillight housing taking care not to damage the locking
tabs.
Step 4
Beginning on the driver side, disconnect the top,
grey connector from the taillight assembly (E). Insert
the custom wiring harness end with the yellow wire
between the separated connectors. Make sure the
connectors are fully inserted with locking tabs in place.
Step 5
Route the remainder of the custom wiring harness to the
passenger side. At the same time push the yellow wire
in between the bumper fascia and the vehicle body.
Step 6
On the passenger side, disconnect the middle, black connector
and insert the custom wiring harness end with the red and
brown wires between the separated connectors. Make sure that
the connectors are fully inserted with locking tabs in place.
Step 7
Disconnect the top, grey connector from the taillight assembly
(E), and insert the custom wiring harness end with the green &
red with white stripe wires between the separated connectors.
Make sure that the connectors are fully inserted with locking tabs
in place.
Step 8
Locate a suitable grounding point near the connector such as
an existing screw with nut in the vehicle frame or drill a 3/32"
pilot hole for the provided screw. The area should be free of
rust, dirt and paint. Secure the white ground wire using the ring
terminal and provided screw.
WARNING: Check for miscellaneous items that may
be hidden behind or under any surface before drilling to avoid
damage and / or personal injury.

Step 9
Disconnect the negative battery cable. Using the
provided ring terminal, attach the fuse holder (with
the fuse removed) to the positive battery terminal.
Step 10
Connect the fuse holder to the black, 12 gauge wire using
the provided yellow butt connector. Route the wire rearward
from the fuse holder, underneath the vehicle along the frame
rail, to the bumper. End at the passenger-side taillight.
WARNING: Make sure to avoid areas that contain moving
parts that could cut, pinch or burn the wires when routing the 4-flat
harness to the rear of the vehicle. Failure to follow these warnings
may cause property damage, personal injury or loss of life.
Step 11
Attach the 12 gauge wire to the blue wire on the
custom wiring harness marked "Battery +" with
the provided yellow butt connector.
Step 12
Open the jack storage compartment cover. From the
outside of the vehicle, pull the rubber grommet surrounding
the passenger-side wiring harness away from the body.
Carefully slit the grommet to allow the wiring harness 4-flat
connector and wires to pass through the grommet and into
the jack storage compartment. Reseat the grommet into the
mounting hole. Retain the 4-flat connector inside the jack
storage compartment for future use. Use the provided sealant
to seal the cut in the grommet and around all the wires (F,G).
Step 13
Reconnect the negative battery cable
and install the provided 10 amp fuse.
Step 14
Locate a flat clean surface that is out of the path of spray
and debris from the rear wheels and road. Adhere the black
converter box using the provided double-sided tape. Failure to
mount the box in a protected area can cause loss of warranty,
product failure, overheating and potential fire.
WARNING: Check for miscellaneous items that may
be hidden behind or under any surface before drilling to avoid
damage and / or personal injury.
Step 15
Reinstall all items removed during install. Install the
provided 4-flat dust cover to help prevent corrosion.
