Curt 56083 T-Connector Wiring Harness - Lexus RX350, RX350L & RX450h - 4-Flat

Vehicle-specific wiring harness plugs directly into the factory tow-package socket without cutting or splicing. Provides a standard 4-way flat connector for trailer tail lights, brake lights, and turn signals.

Why Choose the Curt 56083 T-Connector?

The Curt 56083 provides a simple plug-and-play way to add a standard 4-way flat trailer wiring connection to compatible Lexus RX models equipped with the factory tow package. The vehicle-specific connector plugs directly into the existing OEM tow socket, eliminating the need to cut, splice, or tap into the vehicle's wiring.

Once connected, the 4-way flat output supplies the trailer's basic lighting functions, including tail lights, brake lights, and turn signals. The harness also includes a protective dust cover and slit-loom wire protection for added durability when exposed to normal towing conditions.
