You will need a T-25 Torx head screwdriver to remove the taillight screws. If you do not have a suitable grounding point with an existing screw and nut, you will need a drill with a 3/32" bit. The kit includes double-sided tape, cable ties, an eyelet, and a screw for grounding.
The kit includes a T-connector with yellow and green wires, a 4-flat wire connector, a black converter box, double-sided tape, cable ties, an eyelet, and a screw for grounding.
Open the rear hatch and locate the two T-25 Torx head screws holding each taillight in place. Remove both screws, then carefully pull out on the taillight housing, being sure not to damage the alignment tabs.
Starting on the driver's side, separate the vehicle's taillight wiring connectors without damaging the locking tabs. Insert the T-connector end with the yellow wire between the separated connectors. Ensure the connectors are fully inserted with locking tabs in place. Repeat this process on the passenger side using the green wire connector.
Route the T-connector end with the green wire and the 4-flat wire down through the opening under the driver's side taillight. Route the green wire across the backside of the bumper and up through the opening under the passenger side taillight. Route the 4-flat connector to the center of the vehicle and secure it in a convenient, out-of-the-way location.
Drilling is required only if you do not have a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. If drilling is necessary, drill a 3/32" hole and secure the white wire using the eyelet and screw provided in the kit. Before drilling, verify that no miscellaneous items are hidden behind or under the surface to avoid damage and personal injury.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. If one is available, use it to secure the white wire. If not, drill a 3/32" hole and secure the white wire using the eyelet and screw provided in the kit. Before drilling, verify that no miscellaneous items are hidden behind or under the surface.
Adhere the black converter box to the frame of the vehicle behind the taillight using the double-sided tape provided in the kit.
Secure any loose wires with the cable ties provided in the kit. Route the 4-flat connector to the center of the vehicle and secure it in a convenient, out-of-the-way location.
Before drilling, verify that miscellaneous items are not hidden behind or under any surface. Drilling into hidden wires, fuel lines, or other components can cause damage and personal injury.
