4. Setup and Installation
This kit is designed for easy DIY installation directly into the tail light housings of most vehicles with adequate space. No complicated tools or vehicle modifications are required beyond drilling a 1-inch hole.
4.1 Installation Steps
- Prepare the Tail Light Housing: Locate a suitable area within the towed vehicle's tail light housing to install the new bulb sockets. Ensure there is enough clearance for the bulb and socket assembly.
- Drill Mounting Holes: Using a 1-inch drill bit, carefully drill two holes in the designated areas of the tail light housing.
- Install Bulb Sockets: Insert the two 3-wire automotive sockets into the drilled holes. The sockets are designed to fit securely.
- Insert Bulbs: Install the two 40-watt automotive bulbs into the newly mounted sockets.
- Wire Connections: Connect the wires from the bulb sockets to the appropriate wires of the 26 ft. 4-flat wiring harness. Use the provided butt connectors for secure and insulated connections. The brown and green 16 Ga. wires are for extending connections if needed.
- Grounding: Securely attach the ground wire (typically white) from the harness to the vehicle chassis using one of the provided ring terminals and self-drilling screws. Ensure a clean, paint-free metal surface for optimal grounding.
- Route Wiring Harness: Route the 26 ft. 4-flat wiring harness from the tail light area to the front of the towed vehicle, ensuring it is secured away from moving parts, exhaust, and sharp edges. Leave enough slack to connect to the towing vehicle.
- Connect to Towing Vehicle: Connect the 4-flat plug from the towed vehicle's harness to the corresponding 4-flat receptacle on your RV or towing vehicle.

5. Operating Instructions
Once installed, the sixcow BX8869 Tail Light Wiring Kit operates by receiving signals directly from your towing vehicle's lighting system via the 4-flat connector. This standalone setup ensures that the towed vehicle's lights function independently of its own electrical system.
- Brake Lights: When the towing vehicle's brakes are applied, the towed vehicle's newly installed bulbs will illuminate as brake lights.
- Turn Signals: When the towing vehicle's turn signals are activated, the corresponding side of the towed vehicle's lights will flash.
- Running Lights: When the towing vehicle's headlights or running lights are on, the towed vehicle's lights will illuminate continuously.
Always verify that all lighting functions are working correctly before beginning your journey. The high-output 40-watt bulbs ensure clear and dependable illumination for visibility to other drivers.
6. Maintenance
The sixcow BX8869 kit is constructed with high-quality automotive-grade materials designed for long-term reliability. Regular inspection can help ensure continued performance.
- Inspect Wiring: Periodically check the entire wiring harness for any signs of wear, fraying, cuts, or damage, especially where it might rub against vehicle components. The heavy-duty PVC insulation is weather-resistant, but extreme conditions can still cause wear.
- Check Connections: Ensure all electrical connections, including butt connectors, ring terminals, and the 4-flat plug, are secure and free from corrosion. Clean any visible corrosion with a wire brush and apply dielectric grease if necessary.
- Bulb Functionality: Regularly test all brake, turn, and running light functions to confirm bulbs are working. Replace any burnt-out bulbs promptly.
- Socket Integrity: Inspect the thermoplastic bulb sockets for any cracks or damage. Ensure they remain securely in place within the tail light housing.
