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.

Boating Essentials 5-way trailer wire harnesses act as the link to transmit power and signals from your vehicle to the trailer's electrical system to ensure the trailer's taillights, brake lights, and turn signals operate in sync with your vehicle. The fifth wire is specifically for trailers with surge brakes, as it connects to the reverse light circuit to disengage the brakes when the vehicle is backing up. The ground wire is essential for completing the electrical circuit. These 5-way trailer wire harnesses by Boating Essentials feature color-coded wires to simplify setup and reduce installation errors.
