Installation Instructions for T-One® T-Connector for Hyundai Tucson

Part Numbers:

• 118812

Tools Required:

• Trim Panel Remover
• 10mm Socket & Ratchet or 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 pull the taillights away from the vehicle to expose the wiring harness connectors behind each taillight.
   • Disconnect the connectors, ensuring not to break the locking tabs. Clean all connector surfaces to remove dirt.

2. Remove Interior Panels:

   • Inside the rear cargo area, temporarily remove all floor coverings, cargo trays, and the plastic threshold cover.
   • Warning: Do not remove the vehicle's side trim panels, as this may damage the clips holding the panels in place.

3. Locate the Grommet and Route Wires:

   • Locate the grommet under the vehicle on the driver’s side.
   • Remove the grommet and use fish tape to route the T-Connector ends and the power wire through the grommet hole from inside the vehicle. Seat the grommet securely.

   Note: If an existing vehicle wire passes through the grommet, carefully slit the provided T-Connector’s grommet to allow both wires to pass through. Add silicone rubber (not provided) to seal the grommet.

4. Connect the Driver-Side T-Connector:

   • Route the T-Connector end with the yellow and brown wires up to the driver-side taillight pocket.
   • Insert the yellow wire connector between the taillight socket and the vehicle wiring harness. Ensure all connections are fully seated with locking tabs secure.

5. Route and Connect the Passenger-Side T-Connector:

   • Route the T-Connector end with the green and red wires across the bumper bracket and into the passenger-side taillight pocket.
   • Secure the harness to the bumper using cable ties, avoiding hot pipes, heat shields, or sharp edges.
   • Repeat Step 4 for the passenger-side taillight.

6. Connect the Power Wire:

   • Remove the fuse from the yellow fuse holder. Attach the provided ring terminal to the Positive (+) battery cable and secure it.
   • Connect the other end of the fuse holder to the black 12-gauge wire using the provided yellow butt connector.
   • Route the black power wire along the vehicle’s frame to the rear, avoiding hot pipes, heat shields, fuel tanks, or other hazards.
   • Under the vehicle, connect the black power wire to the red 12-gauge power wire exiting the grommet using the provided butt connector. Apply heat to the splice until the tubing recovers and adhesive flows.

7. Ground the White Wire:

   • Locate a suitable grounding point near the connector, such as an existing ground stud.
   • Clean dirt and rustproofing from the area, drill a 3/32” hole, and secure the white wire using the provided eyelet and screw.
   • Caution: Verify what is behind any surface before drilling to prevent damage or injury.

8. Test the Installation:

   • Ensure all connections are complete. Test the installation with a test light or trailer to verify functionality.

9. Mount the Black Box:

   • Mount the T-One® T-Connector black box on the driver’s side using the provided double-sided tape.
   • Secure the remaining harness with cable ties to prevent damage or rattling.

10. Reassemble the Vehicle:

    • Reinstall the plastic trim panels, threshold cover, storage covers, and floor coverings.
    • Ensure no wires are pinched or damaged.

11. Store the 4-Flat Connector:

    • Store the 4-flat connector in the spare tire compartment when not in use.

Safety Notes:

• Overloading circuits can cause fires. Do not exceed stated product ratings or vehicle manufacturer specifications.
• Always wear safety glasses and follow all safety precautions during installation.

Manufacturer Notes:

• Refer to the vehicle owner’s manual and the instruction sheet for additional details.
• Store these instructions for future reference.
