Maintenance

Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections.

Step 1
Locate the vehicle battery and disconnect the negative battery terminal. Be sure to fasten this wire down and away from the battery while completing the installation process.

Step 2
Open the rear hatch and locate the taillight trim panel. Use a panel trim removal tool to remove the push fastener in the taillight trim and remove the taillight cover.

Step 3
Using a T-27 torx bit, remove the single screw securing the taillight. Remove the taillight at a 45° angle out from the vehicle (Several alignment tabs will only allow the light to be removed in this direction).
Locate the vehicle taillight wiring connectors.
The connectors will be similar to those on your new custom wiring product. Separate the connectors from the taillight housing taking care not to damage the locking tabs.
Set the taillight aside Repeat steps 2 and 3 on the other side of the vehicle.

Step 4
Route a fishwire down between the bumper cover in the further rear opening of the bumper cover and the body of the vehicle. Repeat on the other side of the vehicle.

How to Fishwire

A) Fish wire is a way to push or pull an electrical wire through a blind hole.
Make sure the wire is long enough to stick out on the other side.
Insert the fish wire through the blind hole and locate it on the other side.
B) Use tape to secure the harness to the fish wire and pull back up.
The fish wire or harness may get hung up on something, if this happens you may have to push back down, wiggle it around or twist the wire to loosen it from what it’s hung up on.
Fish wire could be anything from a cut-up wire hanger, stiff wire, rope or string depending on what is needed for the installation.

Step 5
Starting on the passenger side, locate the housing with the green wire on the custom wiring harness. From under the vehicle bumpattach the harness to the fishwire and pull the harness up to the taillight cavity. Attach the custom wiring harness to the vehicle factory wiring and secure to the taillight. Set the taillight inside the taillight cavity, but do not fully install at this time.

Step 6
Route the housing with the yellow wire above the bumper mount and along the bumper to the driver side. Zip tie as needed along the bumper. Route above the driver-side bumper mount.
Repeat step 5 to the housing with the yellow wire.

Step 7
Locate a grounding point such as an existing screw or bolt in the frame of the vehicle or drill a 3/32″pilot hole. The area should be free fromrust, dirt, and paint (abrasive pad/paper to remove rust and paint). Secure the white grounwire with the ring terminal on the existing fastener or with the provided ground screw.

CAUTION
Check for miscellaneous items that may be hidden behind or under any surface before drilling to avoid damage and/or personal injury

Step 8
Route the black power wire from the vehicle battery as shown on the provided ‘Powered Converter Lead Instruction Sheet’.

NOTICE
Once 12 volt power wire is connected to the harness verify that the harness is functioning by attaching the battery and testing with a test light, 4-flat tester or a functioning trailer.
When in use, route the 4-flat to the center of the vehicle and out of the trunk to the trailer. Be sure to stay clear of the trunk’s latching mechanism. When not in use, roll up and store in a convenient, out of the way location. Secure any loose wires with the provided cable ties. Reinstall all items removed during install. If it was disconnected at the beginning of the installation, reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion.
