Step-by-Step Instructions:

1. Access Rear Taillights:

   • Open the vehicle’s rear tailgate.
   • Remove the access panel on the driver’s side and pull out foam from the opening to locate the rear of the taillight. Repeat on the passenger side.
   • Remove the threshold, trunk floor panels, and trays. Set aside all items to prevent damage.

2. Locate Wiring Harness:

   • Identify the vehicle’s taillight wiring harness connected to the taillight socket. This harness will have a connection point matching the T-Connector adapter.
   • Separate the connectors carefully, ensuring no damage to the locking tabs. Verify that all surfaces are clean and free of dirt.

3. Connect T-Connector:

   • On the driver’s side, insert the T-Connector with the yellow wire between the vehicle wiring connectors and lock into place. Ensure all connectors are secure.
   • Route the T-Connector end with the green wire to the passenger side behind the panels and along the threshold. Repeat the connection process for the passenger side.

4. Ground Connection:

   • Locate a suitable grounding point near the connectors, such as the vehicle’s frame or crossmember. Do not drill into exposed surfaces.
   • Clean the area of dirt and rustproofing, drill a 3/32” hole, and secure the white wire using the provided eyelet and screw.

5. Connect Power:

   • Inside the vehicle, connect the black 12-gauge wire from the T-Connector black box to the red wire using the supplied yellow butt connector.
   • Route the black wire to the vehicle’s fuse box under the hood, avoiding areas that could pinch or damage the wire.
   • Attach the yellow fuse holder’s ring terminal to the vehicle’s power cable stud and secure it with a 10mm nut. Connect the other end of the fuse holder to the black wire using the yellow butt connector.

6. Complete Installation:

   • Reconnect the vehicle’s negative (-) battery cable and install the 10-amp fuse into the fuse holder.
   • Secure the remaining T-Connector harness with the provided cable ties to prevent damage or rattling.

7. Test Functionality:

   • Test the installation with a test light or trailer to confirm proper operation. For the initial test, temporarily remove the key from the ignition to reset the vehicle’s electrical system.

8. Reassembly:

   • Reinstall the threshold, storage covers, floor covering, and any other items removed during installation. Ensure no wires are pinched or cut.

   Specifications:

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

Hardware List:

• T-Connector adapter.
• Eyelet and screw.
• Yellow butt connector.
• Yellow fuse holder with 10-amp fuse.
• Cable ties.
