The Tekonsha 118727 Harness is a custom-fit T-One® trailer wiring harness that provides a 4-pole flat connector at the back of your vehicle to power your trailer’s turn signals, br ake lights, and running lights without needing complex wiring changes. It’s designed to plug directly into the factory wiring harness behind the taillights, giving you an easy plug-and-play installation with no cutting or splicing required, and includes a circuit-protected ModuLite® module to help manage electrical load and protect your vehicle’s wiring. Built with weather-proof construction and bonded 16-gauge wire, it offers a reliable towing connection that integrates neatly with your vehicle’s existing electrical system and supports adapters for larger trailer connectors as needed.
