This step-by-step installation guide will walk you through the entire process, from removing the door panels to connecting the wiring and installing the LED light modules. With vehicle-specific components and plug-and-play connectors
PS: The installation package includes four-door illuminated midrange speaker covers. The armrest lights can be connected to the added illuminated speaker cover modules on the doors for power and control, eliminating the need to run additional wiring through all four doors.
If the vehicle already has an aftermarket ambient lighting module installed, no additional module is required. The armrest lights will share the existing interior ambient lighting module for control and power.

Troubleshooting Guide
1. Factory light head does not turn on:
Remove the adapter connecting to the original factory light connector, restore the original connection, then lock the vehicle and let it enter sleep mode for 10 minutes. If the original light works normally after restoration, check the adapter harness, control module, and wiring. If it still does not work after restoration, inspect the factory wiring for pinching, short circuits, or other damage, and perform ambient light addressing/coding.
2. Factory functions are abnormal:
Check whether the original factory connectors have been properly reconnected. Inspect the connectors for bent pins, pushed-back pins, or poor contact issues.
3. Armrest light does not work:
Check whether the right front footwell light is displaying the ambient lighting color. Confirm whether the module adapter is functioning properly. Check whether the door pass-through pin wiring is connected correctly, and inspect the hidden wiring installation for possible pinching, short circuits, or open circuits.
4. Armrest light color is different from other lights:
Adjust and test individual colors:
- Blue: Level 1 or 64
- Green: Level 44
- Red: Level 17
If the corresponding single-color number does not match, check whether the armrest light head is damaged. Inspect the door pass-through pin wiring and hidden wiring installation for short circuits or open circuits.
