Step 1 — Remove the factory center marker light

Step 2 — Disconnect the factory connector

From underneath the truck, locate the center marker connector and unplug it by depressing the locking tab.

Step 3 — Route the new red wire

Set the factory marker light aside. Route the red wire from the new center marker light through the opening in the tailgate.

Step 4 — Position the new center marker light

Pull the red wire through as needed, then align the new center marker light in the factory location.

Step 5 — Reinstall the mounting screws

Reinstall the two factory T30 Torx screws to secure the new center marker light.

Step 6 — Plug in the center marker light connector

Reconnect the center marker light connector until it clicks into place.

Step 7 — Route the red wire toward the taillight

Route the red wire over the frame and toward the taillight connector. Secure it away from any moving parts or sharp edges.

Step 8 — Remove the taillight screws

Lower the tailgate, then remove the two 7mm screws securing the taillight.

Step 9 — Remove the taillight

Carefully pull the taillight straight back to release the alignment pins and remove it from the vehicle.

Step 10 — Connect the red wire to the brake light circuit

Unplug the taillight connector. Identify the brake light wire/pin (on the example truck shown, it was pin 2), then use the supplied T-Tap to connect the red wire to the brake light wire.
