4. Connect Switch to Battery: Connect the main unit. The large terminals on the switch are for the main battery circuit. One terminal connects to the vehicle's main negative cable, and the other connects to the battery's negative post. Ensure the red and black control wires from the switch are connected to the positive and negative terminals of the battery respectively (red to positive, black to negative).
5. Secure Connections: Tighten all nuts and bolts on the terminals to ensure a firm connection. Use the provided dust caps to cover exposed terminals for protection.
6. Test Functionality: Once all connections are secure, reconnect the vehicle's battery (if it was fully disconnected). Use the remote control to test the switch's ON/OFF function. The vehicle's electrical system should power on and off as commanded by the remote.
