Vehicle-specific T-connector that plugs into your Toyota's factory taillight wiring, providing a standard 4-way flat trailer connection with a built-in tail light converter and no cutting or splicing required.
If your Toyota pickup or Tacoma isn't already equipped with wiring for towing a trailer, this Curt custom wiring harness is the solution. Also called a T-connector, it's a simple, plug-and-play electrical device that plugs into your truck's existing electrical system using OEM-compatible connectors at the taillight assembly, eliminating the need for cutting, splicing, or soldering.
Built specifically for select years of the Toyota Pickup (1989-1995) and Tacoma (1995-2004), it includes a tail light converter for proper vehicle-trailer compatibility and provides a standard 4-way flat output to power your trailer's taillights, brake lights, and turn signals. It's constructed with SMT circuitry for better performance and durability, and a dust cover is included to keep the connector clean when not in use.
