The kit includes a custom wiring harness with yellow and green wire ends, a white ground wire with ring terminal, and a provided screw for grounding. A panel trim removal tool is required but the manual does not specify whether it is included in the kit.
You will need a panel trim removal tool to access the taillight wiring. A drill may be required if a suitable existing grounding point is not available. A test light, 4-flat tester, or functioning trailer is needed to verify proper function after installation.
Yes. Step 1 requires you to locate the vehicle's battery in the engine compartment on the driver side and disconnect the negative battery terminal. Fasten this wire down and away from the battery while completing the installation.
1. Locate the vehicle's taillight wiring harness on each side behind the taillights. 2. Disconnect the vehicle harness connectors on the driver side. 3. Position the custom wiring end with the yellow wire between the separated vehicle connectors. 4. Firmly press the connector ends together until the locking tabs engage, taking care not to damage the alignment tabs. 5. Repeat on the passenger side using the custom wiring end with the green wire.
Route the custom wiring end with the green wire out from under the trim panel and along the threshold to the passenger side of the vehicle. The yellow wire end connects on the driver side and the green wire end connects on the passenger side.
Not necessarily. First, 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, drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt, and paint. Before drilling, check for miscellaneous items hidden behind or under surfaces to avoid damage and personal injury.
Drill a 3/32" pilot hole if an existing grounding point is not available. The area should be free of rust, dirt, and paint before securing the white ground wire using the ring terminal and provided screw.
