This diagram illustrates the connections for the left and right lights, showing the yellow wire connecting to the vehicle's left stop & turn light, the white wire as the ground, the brown wire for running lights, and the green wire for the right stop & turn light.
- Connect the YELLOW wire of the Trunk Harness to the vehicle's Left Stop & Turn light.
- Attach the WHITE GROUND wire to the towing vehicle's frame. This provides the necessary ground connection for the electrical circuit.
- Connect the BROWN wire of the Trunk Harness to the towing vehicle's Running Lights wire.
- Connect the GREEN wire to the towing vehicle's Right Stop & Turn light.
Ensure all connections are secure and properly insulated to prevent corrosion and electrical issues, especially for submersible applications. Before submerging the lights, verify there are no electronic shorts in the wiring.

- Running Lights: Activate when the vehicle's headlights or parking lights are on.
- Stop Lights: Activate when the vehicle's brake pedal is pressed.
- Turn Signal Lights: Activate when the vehicle's left or right turn signal is engaged.

Maintenance
The CZC AUTO trailer lights are designed for durability and minimal maintenance. However, regular checks can extend their lifespan and ensure continued safe operation.
- Regular Inspection: Periodically check the lights for any physical damage, such as cracks in the lens or housing.
- Wiring Check: Inspect wiring connections for corrosion, fraying, or loose contacts. Clean and re-secure as necessary.
- Cleanliness: Keep the light lenses clean from dirt, mud, or salt residue to ensure maximum light output. Use a soft cloth and mild soap if needed.
- Waterproofing Integrity: While designed to be submersible, occasionally check the seals around the wires and lens edges, especially after prolonged submersion or exposure to harsh conditions.

The lights achieve their waterproofness through Sonic Welding Whole Sealing Technology, 18 gauge 100% Pure Copper Wires for submersible use, and sealing of every possible gap with glue, such as the edges of the lens and wire entry points. A 100% quality inspection, including photometric testing, is performed before shipping.
