The control box requires connection to the vehicle's ACC (Accessory) power to operate normally. Follow these steps for proper wiring:
- Connect the red wire from the control box to the positive (+) terminal of the vehicle's battery.
- Connect the blue wire from the control box to the ACC power source. This ensures the panel operates only when the vehicle's ignition is on.

- Connect your auxiliary devices (e.g., LED Headlights, Wheel Lights, Whip Lights, Driving Lights, Light Bar, Underglow Lights) to the numbered output terminals (1-4) on the control box.
