1. Access the factory taillight

Remove the rear interior access panel with a plastic trim tool. Remove the two 10 mm fasteners holding the taillight.

2. Disconnect and remove the assembly

Press the connector release and unplug it. Pull the taillight directly rearward from its locating mounts.

3. Install the modules inline

Connect the module between the factory wiring and taillight. Reinstall the light and its fasteners; repeat on the other side. This completes the module-only installation.

4. Identify the former turn-signal lead

Only continue for the optional additional-backup conversion. Identify the module lead connected to the original turn-signal socket, as shown in the source photograph.

5. Identify the green reverse wire

Locate the green backup-light wire on the module. Use the manufacturer’s illustrated wire identification; do not select a vehicle wire solely by a guessed colour.

6. Attach the supplied T-tap

Place that green wire in the connector’s metal groove, fold the T-tap around it and close it with pliers as directed.

7. Connect the former turn lead

Plug the identified turn-signal lead into the T-tap. Repeat on the other module and reconnect the modules.

8. Install compatible white LEDs and test

Replace the former turn-signal bulbs with the compatible white LEDs included in the selected Stage package. Incandescent bulbs must not be used for this additional-light conversion because they draw too much current. Check tail, brake, turn and reverse operation. Module resistors can become hot during prolonged turn-signal use.
