## Description

CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special socket is not equipped on every vehicle, a CURT custom wiring connector -- also called a T-connector -- utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Subaru Ascent, Forester, Outback, Crosstrek and XV Crosstrek (to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it.

## Questions & Answers

**Q: Where is connector located in  2015 Subaru Outback ?**
A: Not sure where it is in the 2015 Outback but in my 2009 Forester it was on the drivers side underneath the foam storage inserts in the trunk.

**Q: 2003 tacoma**
A: I can only say it worked great on my 2013 Subaru outback hope that helps

**Q: wear is the plug on a 2013 outback**
A: for a '15 crosstrek it's behind the trim panel covering the back of the driver side taillight, down near the floor. Had to remove the trim panel just inside of lower weatherstripping for lift gate first; I think the instructions indicated that for an outback it's farther forward, nearer the wheelwell.

**Q: Has anyone installed this in a 2015 Subaru Impreza?**
A: I was wondering the same thing, so I pulled the trim panels out of the back of my 2015 Impreza Sport Hatchback. Based on a video of the Crosstrek install of this part, there is a small white plug under the driver's side taillight in the Crosstrek that this plugs into. The plug is non-existent in my Impreza. I checked under the passenger side too just in case, but no luck.
