Installation Instructions
Step 1 — Open the trunk and remove the plastic push clip securing the trunk carpet, then peel the carpet back to access the taillight mounting area.
Step 2 — Using an 8mm socket, remove the four nuts securing the taillight to the vehicle.
Step 3 — Carefully pull the taillight straight back from the vehicle and disconnect the factory taillight connector.
Step 4 — Plug the supplied inline harness into the vehicle's taillight connector.
Step 5 — Route the inline harness connector downward behind the rear bumper, feeding it toward the lower bumper opening.
Step 6 — Reconnect the inline harness to the taillight, reinstall the taillight, and secure it using the four factory 8mm nuts.
Step 7 — Reach behind the rear bumper and push out the lower plastic trim, then remove it completely and set it aside.
Step 8 — Slide the provided clip nuts onto the mounting bracket, then insert the LED brake light into the bracket.
Step 9 — Using the supplied Torx screws, secure the LED brake light to the mounting bracket.
Step 10 — Connect the safety strobe module to the routed harness connector. Leave the purple wire connected to enable brake light strobing.
Step 11 — Feed the connector from the safety strobe module through the lower bumper cavity toward the mounting location.
Step 12 — Carefully trim a small square opening in the back of the bumper pocket so the light can sit flush once installed.
Step 13 — Connect the harness to the LED brake light, then position the assembly into the bumper opening. Install the mounting bolts with washers from behind the bumper and tighten securely using an 8mm socket.
Step 14 — Trim the center opening of the lower plastic trim as marked, reinstall it onto the vehicle, and zip tie any loose wiring.
Step 15 — Test the brake light for proper operation. The install is complete.
