Description

The CURT 56458 is a vehicle-side custom wiring harness designed for select Toyota Sienna models. This harness provides a 4-way flat output, allowing you to connect your trailer's tail lights and brake lights.

It features a simple plug-and-play design that connects directly to your vehicle's taillight assembly, eliminating the need for cutting, splicing, or soldering wires. The harness includes a tail light converter to ensure compatibility between your vehicle and trailer's electrical systems. It also comes with a dust cover to protect the connector when not in use and is backed by a one-year limited warranty.
