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 a plug-and-play connector, a custom wiring connector easily integrates with your vehicle to provide a standard trailer wiring connector, typically in the form of a 4-way flat.
This custom wiring connector features a vehicle-specific design to perfectly fit certain years of the Subaru Ascent, Forester, Outback, Crosstrek and XV Crosstrek (to verify vehicle compatibility, see the CURT application guide or use the Vehicle Lookup on the CURT website). It uses an OEM-compatible connector to plug into the vehicle's OEM socket 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 connector, 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.

Excellent Quality and simple installation. Highly recommend this product and company. FYI - Very reasonable price. Subaru quoted $149 w/o installation.

Just wanted to leave a quick note regarding this product. Really impressed with the kit. Very solid construction and the additional ties, connectors, and fuse are an added bonus. However, the instructions are incorrect for the 2022 Outback. In the instructions it shows the factory plug to be under the rear driver side wheel cover. It is actually at the rear door, same as the 2021. Lost about an hour trying to find a connection point in the wrong place. Other than that, it’s a great product and I would highly recommend.

This product works well, and is easy to install, but the installation instructions are incorrect for the 2019+ model year Forester. Specifically, you only need to remove the driver side foam tray, (there is no back one), and you do not need to remove the rear trim panel, instead locate the wiring harness connector directly at the back left (drivers side).
