    • Using a drill or a knife, make a hole in the middle of the rubber grommet large enough to fit the 3 wires coming from the rear of the new 3rd brake light.

Rear Bumper Plastic Insert Removal:

  • By hand, lightly use the screws to attach the bracket to the 3rd brake light. Ensure the brake light is straight then finally use a screwdriver to tightly fasten the bracket to the brake light.
  • Take the wiring harness from the 3rd brake light and fish it up through the back of the rear bumper, through the hole that the rubber grommet covered.
  • Pull the wires through the hole you created in the rubber grommet.

 Wiring the 3rd brake light:

  • Find the connector that is plugged into the back of the tail light harness and unplug it.
