Installation of RGB DRL Boards

If you're installing RGB boards, the process remains largely the same as described above. However, additional steps are required due to the color-changing feature inherent to RGB boards.


Board Installation:

  1. Install the RGB boards following the same steps outlined in the general installation guide above.


Power Connection:

  1. After installing the RGB boards, connect the harness and Bluetooth module to a switched power source located in the engine bay fuse box.


Setting Up the Controller:

  1. Once the power connection is established, extend the wiring harness from the boards to the RGB controller. This controller is the hub for controlling the RGB feature.


App Setup:

  1. A QR code is provided on the back of the RGB controller. Scan this QR code to download the corresponding app for controlling the RGB lights.


By adhering to these steps, you'll be equipped to successfully install and enjoy the features of your new RGB boards. Handle all components with care to ensure the best results and longevity of your new LED lights.
