Rewiring your trailer's lights? This Aufind wiring harness kit has everything you need. It's a 4-pin flat connector system with 5 actual wires (18 AWG pure copper with tinned ends to resist corrosion), providing a direct connection for left/right tail lights, brake lights, and turn signals. The main harness is 30 feet long, plus there's a 2.5-foot ground wire, giving you plenty of length to route it neatly on most trailers. The wires are color-coded for easy installation and are protected by a thick PVC coating and a tough outer braided nylon sleeve for durability against weather and abrasion. The kit includes a Y-harness connector, wire clips, solder seal connectors, and plastic connectors to help with the job. Perfect for rewiring boat trailers, utility trailers, or ATV trailers. Just make sure your tow vehicle and trailer use a standard 4-way flat plug system.
