8. Raise the passenger side bracket into place over the muffler. Loosely install the M12 bolt and conical washer through the bracket into the driver-side frame rail. Install the 1/2" conical washers (teeth side against hitch) and 1/2" nuts onto the carriage bolts.
9. Torque all 1/2" fasteners to 75 ft-lbs (102 N·m) and the M12 bolt to 68 ft-lbs (92 N·m).
10. Reinstall the exhaust hangers.
11. Reinstall wiring and bumper fascia.

   • Inside the vehicle, remove the plastic cover and pull back the insulation liner to access the plastic wing nut holding the taillight.
   • Unscrew the wing nut and carefully pry the taillight assembly away from the vehicle.
   • Repeat for the passenger side.

2. Connect the T-Connector on the Driver’s Side:

   • Disconnect the vehicle’s wiring harness from the taillight socket.
   • Plug the T-Connector with the yellow wire between the taillight socket and the vehicle wiring harness.

3. Route the Wiring Harness:

   • Route the T-Connector end with the green wire and the 4-flat connector down through the opening between the vehicle bumper and body.
   • Route the T-Connector with the green wire to the passenger side underneath the bumper.
   • Carefully route the green wire up through the passenger-side opening and connect it to the passenger-side taillight harness.

   Warning: Avoid routing the wire near hot pipes, heat shields, the fuel tank, or any sharp edges that could pinch or damage the wire.

4. Ground the White Wire:

   • Locate a suitable grounding point near the driver-side taillight, such as the vehicle’s frame or crossmember.
   • Clean the area to remove dirt and rustproofing.
   • Drill a 3/32” hole and secure the white wire using the provided eyelet and screw.

   Caution: Ensure no damage will occur behind the surface before drilling.
