Trailer Wiring Harnesses
Trailer wiring harnesses connect a trailer's lighting circuit to a pre-wired socket or vehicle junction box, carrying the signals for indicators, brake lights, and rear lights. They are typically supplied with bare or spade-terminated wire ends for splicing into the trailer's existing wiring, and are used when replacing damaged cabling or fitting a new socket to horseboxes, livestock trailers, and other towed equipment. Available in 7-pin, 12N, and 13-pin configurations to match different socket and pin standards.
