5. Installation Instructions

This LED third brake light is designed for "Plug-n-Play" operation, meaning it is a direct bolt-on replacement for the original equipment (OE) unit. It uses existing bolt holes for installation. Professional installation is highly recommended.

5.1 Tools Required (Not Included)

  • Basic hand tools (e.g., screwdriver, socket wrench set)
  • Wire strippers/crimpers (if modifications are needed for cargo light)
  • Electrical tape or heat shrink tubing (if modifications are needed)

5.2 General Installation Steps

  1. Prepare Vehicle: Park the vehicle on a level surface and engage the parking brake. Disconnect the negative terminal of the vehicle's battery to prevent electrical shock or damage to the vehicle's electrical system.
  2. Access Original Brake Light: Locate the original third brake light assembly. Depending on your vehicle model, this may involve removing interior trim panels or accessing from the exterior. Refer to your vehicle's service manual for specific removal procedures.
  3. Remove Original Light: Carefully unbolt or unclip the original third brake light. Disconnect the electrical connector from the original unit.
  4. Inspect Wiring: The new LED third brake light may have three color wires for the cargo light function, depending on your factory wiring harness.

  5. Connect New Light: Connect the electrical connector from the vehicle's harness to the new DNA MOTORING LED third brake light. Ensure a secure connection.
  6. Install New Light: Position the new LED third brake light into the opening. Secure it using the existing bolt holes. Apply firm, even pressure to ensure it seats correctly. Note: Avoid excessive force or electronic tools during installation to prevent damage to the product.
  7. Test Functionality: Reconnect the vehicle's battery. Test the brake light function by pressing the brake pedal. Test the cargo light function (if applicable) by activating the appropriate switch.
  8. Final Assembly: Reinstall any removed trim panels or covers.

5.3 Cargo Light Wiring Modifications (If Applicable)

If your vehicle is not equipped with a cargo light but you wish to install this feature, or if you experience the cargo light staying on constantly, two modifications may be performed:

  • Disable Cargo Light Function: This can be done by cutting the white 12V cargo light power wire. If this method is chosen, it is recommended to cover the wire end with heat shrink tubing, wire nuts, or electrical tape to prevent short circuits.
  • Add a Switch and Run a 12V Power Wire: Add a switch and run a new 12V power wire from your dashboard to the LED brake light. This will also require cutting the white 12V cargo light power wire. Ensure to cover the plug side of the LED wire to prevent electrical issues.
