Tekonsha 118240 Trailer Wiring Harness Assembly

The Tekonsha 118240 Trailer Wiring Harness Assembly provides a reliable 4‑way flat trailer lighting connection between a tow vehicle and a trailer. A vehicle‑specific T‑One connector, it plugs directly into the factory wiring on 1996–2003 Chevrolet Express and GMC Savana vans equipped with the factory tow package, delivering stop, turn, tail, and running light signals without cutting or splicing. The harness uses 16 AWG bonded wire with a 4.2 A stop/turn circuit and a 7.5 A tail light circuit, and it arrives as a one‑piece weatherproof assembly with an integrated dust cap. Designed for towing utility trailers, boat trailers, cargo trailers, recreational trailers, and other light‑duty systems, it supports plug‑and‑play installation and is backed by a 1‑year limited warranty.
