Open the vehicle trunk. Remove the fasteners securing the felt trunk liner on the driver side and pull it back. You will see plastic wing nuts securing the taillight assembly. Remove the three plastic wing nuts, then locate and separate the vehicle taillight wiring harness connectors from the taillight housing. Take care not to damage the locking tabs. Repeat this process on the passenger side.
Open the vehicle tailgate. Remove the two bolts securing the taillight assembly on the driver side, then remove the taillight assembly to locate the vehicle taillight wiring harness connectors. Separate the connectors from the taillight housing, taking care not to damage the locking tabs. Repeat this process on the passenger side.
Insert the custom wiring harness end with the yellow wire between the separated vehicle taillight connectors. Make sure the connectors are fully inserted with locking tabs in place.
Route the custom wiring harness end with the green wire down through the opening underneath the taillight assembly. Route the wire along the backside of the bumper and up through the opening on the passenger side. Then repeat the taillight connection process on the passenger side using the harness end with the green wire.
Drilling may be required to establish a ground connection. You should locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable existing point is available, you may need to drill a 3/32" pilot hole for the provided screw. The area should be free of rust, dirt and paint before securing the white ground wire.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating and potential fire.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
When not in use, roll up the 4-flat connector and store it in a convenient, out of the way location. When in use, route the 4-flat to the center of the vehicle. Secure any loose wires with the provided cable ties.
Reinstall all items removed during installation and reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion. Test for proper function by using a test light or connecting a properly wired trailer.
The white ground wire provides the ground connection for the wiring harness. It should be secured using the ring terminal and provided screw to a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame, or to a 3/32" pilot hole you drill in the frame.
