2. Setup and Installation
Installation of the LED illumination kit requires basic automotive wiring knowledge. It is recommended to perform this installation in a well-lit area with appropriate tools.
2.1 Pre-Installation Checklist
- Ensure the vehicle's ignition is off and the battery is disconnected to prevent electrical shorts.
- Gather necessary tools: wire strippers, electrical tape or heat shrink tubing, zip ties (optional for wire management).
- Clean the inner surface of the fender emblem where the LED strip will be adhered.
2.2 Installation Steps
- Positioning the LED Strip: Carefully line up the LED light strip so that the wire exits from the top of the emblem. Ensure the LED lights are facing inwards towards the emblem's chrome surface for optimal illumination.
- Wire Routing: Gently run the wires through the top slit or gap of the fender emblem. This allows for a clean and concealed wire path.
- Adhesion: Remove the protective film from the adhesive backing on the LED strip. Carefully press the LED strip onto the inside lip of the emblem, applying firm but gentle pressure with your thumb to ensure secure adhesion.
- Accessing Wiring: Open the vehicle's hood to gain access to the headlight wiring harness.
- Electrical Connection: The 6-foot wires from the LED strip need to be tapped into the vehicle's headlight positive and negative wires. For a 2019 Lariat model, the positive wire is typically blue and green, located at the bottom left in the harness. Identify the correct positive and negative wires for your specific vehicle model and year. Use appropriate wire tapping connectors or solder and insulate the connections securely.
- Testing: Reconnect the vehicle's battery and test the LED illumination kit by turning on the headlights.
- Wire Management: Secure any loose wiring using zip ties to prevent interference with moving parts or exposure to elements.

4. Maintenance and Care
The iJDMTOY LED Background Illumination Kit is designed for durability and minimal maintenance. Adhering to the following guidelines will help ensure its longevity.
4.1 General Care
- Periodically inspect the wiring connections to ensure they remain secure and free from corrosion.
- Keep the emblem area clean from excessive dirt and debris, which could potentially obscure the light output.
4.2 Important Considerations
Warning:
Although the LED board is treated to be water-resistant (IP55 rated), the individual LED diodes are exposed. To prevent damage, avoid excessively bending the LED strip or pressing on the LEDs with sharp objects during installation or maintenance. Excessive force or improper handling can compromise the integrity of the diodes and the circuit board.
5. Troubleshooting
