5. Installation
5.1. Preparation
- Gather necessary tools: drill, screwdriver, wire strippers, electrical tape, and cleaning supplies.
- Choose desired mounting locations for each rock light pod. Ensure surfaces are clean and dry.
- Plan the wiring path to the vehicle's 12V power source (battery or ACC circuit) and, if desired, the brake light system.
5.2. Wiring Connection
The wiring harness includes three main wires:
- Red Wire: Connect to the vehicle's positive (+) 12V DC power source (e.g., battery positive terminal or ACC circuit).
- Black Wire: Connect to the vehicle's negative (-) terminal or a chassis ground point.
- Blue Wire: (Optional) Connect to the vehicle's brake light positive wire to enable the brake warning function (all lights turn red when brakes are applied). If this feature is not desired, insulate the blue wire securely.
Ensure all connections are secure and insulated to prevent short circuits.
