Tekonsha's 118896 is a T-One T-connector wiring harness cut for 2025 GMC Terrain. It plugs straight into the vehicle's factory wiring connectors behind the taillights, so no cutting or splicing is needed. The trailer end is a 4-Way Flat connector, and a circuit-protected ModuLite HD module keeps the trailer lighting isolated from the vehicle's electrical system. Rated to 5A on stop and turn and 7.5A on the taillight circuit. Suits a 2-wire system vehicle.
