Tools Required:

• Trim Panel Remover
• 10mm Socket & Ratchet or 10mm Wrench
• Drill (3/32” Drill Bit)
• Fish Tape
• Test Probe
• Utility Knife

Step-by-Step Instructions:

1. Remove the Taillight Assemblies:

   • Open the tailgate and carefully remove the vehicle’s taillight assemblies.
   • Pull the taillight housing away from the vehicle to expose the wiring harness connectors in the pocket behind the taillight.

2. Disconnect the Wiring Harness:

   • Locate the connection points matching the T-Connector adapter ends behind each taillight housing.
   • Disconnect the wiring harness from both taillight sockets. Ensure all connectors are clean and free of dirt.

3. Prepare the Cargo Area:

   • Inside the rear cargo area, temporarily remove all floor coverings, cargo trays, and the plastic threshold cover.
   • Warning: Do not remove vehicle side trim panels to avoid breaking the clips that secure them.

4. Route the T-Connector Wiring:

   • Locate the grommet under the vehicle on the driver’s side. Remove the grommet.
   • Fish both T-Connector ends and the power wire through the grommet hole from inside the vehicle.

   Note:

   • If a vehicle wire passes through the existing grommet, carefully slit the T-Connector’s grommet to allow the wire to pass through.
   • Seal the grommet with silicone rubber (not provided).

5. Connect the Driver-Side T-Connector:

   • Route the T-Connector end with yellow/brown wires up from under the vehicle into the driver’s side taillight pocket.
   • Plug the T-Connector into the driver-side wiring connectors, ensuring the locking tabs are secure.

6. Connect the Passenger-Side T-Connector:

   • Route the T-Connector end with green/red wires over the bumper bracket and across to the passenger-side taillight pocket.
   • Secure the harness to the bumper using cable ties, avoiding hot pipes, heat shields, or areas that may damage the wires.
   • Repeat Step 5 for the passenger-side T-Connector.

7. Connect the Power Wire:

   • Remove the fuse from the yellow fuse holder.
   • Attach the ring terminal to the positive (+) battery cable and connect the fuse holder to the black 12-gauge wire using the provided yellow butt connector.
   • Route the black wire rearward along the frame rail, avoiding hot pipes, heat shields, and the fuel tank.
   • Connect the black wire to the red 12-gauge power wire exiting the grommet using a butt connector.

   Note:

   • Apply heat to the splice using a hot air gun until the tubing recovers and adhesive flows.

8. Ground the White Wire:

   • Locate a suitable grounding point near the connector (e.g., an existing ground stud).
   • Clean the area and secure the white wire using the provided eyelet and screw.
   • Caution: Verify what is behind any surface before drilling to avoid damage or injury.

9. Test the Installation:

   • Test and verify the installation with a test light or trailer.
   • Ensure all connections are complete for the T-Connector to function properly.

10. Mount the Black Box:

    • Mount the T-Connector black box using the provided double-sided tape.
    • Secure the remaining T-Connector harness with cable ties to prevent damage or rattling.

11. Reassemble the Vehicle:

    • Reinstall the plastic trim panels, threshold, storage covers, floor coverings, and other items removed during installation.
    • Store the 4-flat connector in the spare tire compartment when not in use.

    Specifications:

    • Max. stop/turn light: 1 per side (2.1 amps)
    • Max. tail lights: (5.6 amps)

Safety Notes:

• Overloading circuits can cause fires. Do not exceed the towing manufacturer’s rating or the specified maximum ratings.
• Always wear safety glasses and follow safety precautions during installation.
