Boating Essentials 4-Way Trunk Side Trailer Wire Harnesses

Boating Essentials 4-way trunk side trailer wire harness provides the electrical connection needed for a trailer's essential lights, allowing it to be safely and legally towed. The harness connects the vehicle's brake lights, turn signals, and running lights to the trailer's corresponding lights, with a standard configuration of four wires for these functions, plus a ground. The "trunk side" and "wishbone" design helps simplify installation by splitting the wiring to run down each side of the trailer from a central connector, therefore eliminating the need for a separate jumper wire. These wiring harnesses are built with 12-volt DC specifications and color-coded for an easy installation. Show Less
