Description

The Curt 56310 is a vehicle-side custom 4-pin trailer wiring harness designed for select Mazda CX-5 models. This plug-and-play T-connector integrates into your vehicle's electrical system, providing a standard 4-way flat connector for towing.

It eliminates the need for cutting, splicing, or soldering by utilizing OEM-compatible connectors that plug directly into the taillight assembly. The harness comes with all necessary wiring components, including a dust cover for the connector when not in use.
