Product Description

Get your vehicle trailer-ready with the CURT Custom Wiring Harness, designed for a seamless plug-and-play connection. This vehicle-specific harness integrates directly with your Toyota Sienna’s factory taillight system, providing a standard 4-way flat connector to power your trailer’s tail lights, brake lights, and turn signals.

Built for convenience and reliability, this harness eliminates the need for cutting or splicing wires. It features OEM-compatible connectors that “T” into your vehicle’s existing wiring, along with a powered converter to ensure safe and consistent signal output. A protective dust cover keeps the connector clean when not in use, and it can be easily mounted to your hitch using an optional bracket for quick access.
