Lcrslitx 100FT 4-Way Trailer Wire – 14 AWG, 30% Copper Content, Weatherproof Color-Coded Harness for RV, Boat, Utility

Experience dependable trailer lighting on long hauls with the Lcrslitx 100FT 4-Way Trailer Wire. Built with 30% copper-content CCA, this harness is designed to deliver lower electrical resistance and steadier current to tail lights, brake signals, and turn indicators across demanding routes.

Designed for real world use, the wire is sheathed in a heavy-duty black PVC jacket and keeps its flexibility across a wide temperature range. Four individually insulated conductors are color-coded for quick, error-free connections—the white wire is ground, brown runs the tail lights, yellow controls driver-side signals, and green handles passenger-side signals.

Key benefits at a glance

• 30% copper-content CCA conductor for improved conductivity and potential brighter signals.
• Full 100 feet of 14 AWG wire, SAE J1128 compliant for standard 12V trailer lighting systems.
• Weatherproof construction resists moisture, UV exposure, road salt, and oils, while maintaining insulation integrity from -15°C to +105°C.
• Color-coded construction simplifies installation and reduces connection errors for both DIYers and professionals.

Versatile enough for RVs, boats, campers, utility trailers, and more, this 4-pin harness aligns with common trailer wiring standards. The color-coding helps you match wires to existing harnesses and connectors, enabling smoother upgrades or repairs.

Real-world use scenarios

• Long highway trips where reliable signaling contributes to safety and visibility.
• Seasonal trips to lakes or campsites, where moisture and road salt are considerations and a robust harness can maintain performance.
• DIY trailer builds or retrofits requiring a true 100 ft run without mid-run splices.

Support is part of the package. If you encounter any issues with your trailer wiring, dedicated customer service is ready to assist and resolve concerns promptly.

Installation tips and best practices

• Follow the standard color convention: white ground, brown tail lights, yellow driver-side, green passenger-side.
