   • Insert the green wire up through the passenger-side opening and connect it between the taillight socket and the vehicle wiring harness.

   Note: For alternate routing, pull back the fascia area below the tailgate weatherstrip and place the wire behind the fascia. Removal of several fasteners may be required.

5. Ground the White Wire:

   • Locate a suitable grounding point near the connector.
   • 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 the area behind any surface before drilling to avoid damage or injury.

9. Mount the Black Box:

   • Locate a flat, out-of-the-way surface on the driver’s side and secure the T-One® Connector’s black converter box with the provided double-sided tape.
   • Ensure the epoxy side faces downward to prevent water accumulation.

10. Reinstall the Taillight Assemblies:

    • Reinstall the taillights, positioning the vehicle wiring harness between the housing and the vehicle body.
    • Secure the remaining T-One® Connector harness under the bumper with the provided cable ties, avoiding areas that could pinch or cut the wire.
