4-Pin CURT Vehicle-Side Custom Trailer Wiring Harness, Fits Select Toyota Yaris

If your vehicle lacks wiring for towing a trailer, CURT custom wiring serves as the ideal solution.

A custom wiring harness, also known as a T-connector, is a simple, plug-and-play electrical device that connects to your automotive electric system and provides a standard, universal trailer wiring connection.

This is achieved using two or more vehicle-specific, OEM-compatible connectors that plug into the taillight assembly, eliminating the need for cutting, splicing, and soldering during installation.

Custom wiring harnesses are vehicle-specific, and while not available for all vehicles, they offer one of the fastest, easiest, and most secure methods to wire a vehicle for towing.

This particular plug-in harness provides a 4-way flat connector socket and is designed as a custom wiring harness to fit certain years of the Toyota Yaris (to verify your vehicle compatibility, see application info).

It includes all necessary wiring components to establish a reliable trailer wiring connection, along with a dust cover to keep the connector clean when not in use.

You may have a picture in mind of your next destination, whether it's the boat landing at your favorite fishing spot, a campsite overlooking nature's masterpieces, or the next big jobsite.

However, turning that picture into reality requires more than just daydreaming.

It necessitates a solid connection and the right amount of power.

CURT custom wiring is crafted with some of the most sophisticated technology in the industry and is designed for easy installation, providing a long-lasting electrical connection for your towing hitch setup.
