Setup and Installation
Follow these steps for proper installation of the wiring harness kit:
- Plan Your Layout: Determine the mounting location for the 4-gang rocker switch panel and the placement of your LED lights or other accessories. Consider wire routing to ensure sufficient length and protection from heat or moving parts.
- Disconnect Battery: Before starting any wiring, disconnect the negative terminal of your vehicle's battery to prevent electrical hazards.
- Mount the Switch Panel: Install the 4-gang rocker switch panel in your desired location. Ensure it is securely fastened and accessible.
- Connect to Power Source: Connect the main power input wires of the harness to your vehicle's 12V battery. The harness includes a power relay and inline blade fuse for protection. Ensure the positive (+) and negative (-) connections are correct.
- Connect Relays: The harness is pre-wired with relays. These relays manage the power distribution to your accessories, protecting the switches from high current loads.
- Connect Accessories: Each switch on the panel controls two leads. Connect your LED lights or other 12V accessories to the corresponding leads. For example, you can connect up to 8 lights, with each switch controlling a pair of lights.
- Secure Wiring: Route all wiring safely, away from hot engine components, sharp edges, and moving parts. Use zip ties or cable clamps to secure the harness.
- Reconnect Battery: Once all connections are made and secured, reconnect the negative terminal of your vehicle's battery.
- Test Functionality: Turn on each switch to verify that your connected accessories function correctly.

Maintenance
Regular maintenance ensures the longevity and safe operation of your wiring harness kit.
- Inspect Wiring: Periodically check all wiring for signs of wear, fraying, or damage. Ensure connections remain tight and secure.
- Fuse Replacement: The harness is protected by inline blade fuses. If an accessory stops working, check the corresponding fuse. Replace blown fuses only with fuses of the same amperage rating. The kit includes spare fuses (15A, 25A, 40A).
- Clean Components: Keep the switch panel and connectors clean and free from dirt or debris.

Troubleshooting
If you encounter issues with your wiring harness kit, consider the following:
- No Power to Accessories:
- Check if the main power connection to the battery is secure.
- Verify that the inline blade fuse is not blown. Replace if necessary.
- Ensure the switch is in the ON position and its indicator light is illuminated.
- Inspect the connections between the harness leads and the accessories.
- Switch Not Functioning:
- Ensure the switch is properly connected to the harness.
- Check for any visible damage to the switch or its terminals.
- Fuses Blowing Repeatedly:
- This indicates an overload or a short circuit. Disconnect accessories and test circuits individually.
- Ensure the total wattage of connected accessories does not exceed the harness's capacity or the individual wire gauge limits.
- Inspect wiring for any exposed wires touching metal or other wires.
