WARNING: Cancer and Reproductive Harm -

Making memories doesn't start when you reach your destination; it starts at the very first mile of your journey. Wherever your road begins and wherever it takes you, Bring It® with the power of CURT.

CURT custom wiring provides everything you need to connect your vehicle's electrical system to a trailer. With plug-and-play connectors, a custom wiring harness easily integrates with your vehicle taillights to provide a standard trailer wiring connector, typically in the form of a 4-way flat.

This custom wiring harness features a vehicle-specific design to perfectly fit certain years of the Subaru Impreza, Subaru BRZ and Scion FRS (to verify vehicle compatibility, see the CURT application guide or use the Vehicle Lookup on the CURT website). It uses OEM-compatible connectors to "T" into the vehicle's taillight assembly and provides a standard 4-way flat output to power the taillights, brake lights and turn signals on your trailer.

To complete this custom wiring harness, it comes with a rubber dust cover. This cover keeps the connection points clean and well protected when the connector is not in use. Once installed, the connector can also be conveniently mounted on the vehicle's trailer hitch receiver tube, using a CURT Easy-Mount connector bracket. The bracket mounts onto the trailer hitch with no drilling required, and its powder-coated steel construction provides a solid attachment point for plugging in the trailer wiring.
