## Overview

The CURT 55370 is a custom 4-pin trailer wiring harness designed specifically for select Subaru models, offering a simple plug-and-play installation with no cutting or splicing required.

## 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 Forester, Legacy, Outback wagon, Tribeca, B9 Tribeca and Impreza WRX wagon (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.

- Simple plug-and-play design eliminates the need for cutting or splicing
- 4-way flat output connects tail lights, brake lights and turn signals
- Equipped with tail light converter for vehicle-trailer compatibility

## Questions & Answers

**Q: Can some wiring kits be faulty?**
A: I worked at a parts store that sold Curt products and I never found a faulty kit.  Make sure that all your connections are clean and well connected.  Also, make sure that your existing wiring is not the problem.  Also, make sure you route wires so that they are not pinched or stretched.

**Q: Why wouldnt this work for the 06 outback impreza?**
A: Chances are it will. My care is a 2006 Impreza Outback. I found the connector on the passenger side, in the trunk, just behind the rear tail light. If you can find a rectangle white 6 prong (2x3) connector then you've probably got it.

**Q: does this provide power to the brakes in the trailer?**
A: No....

**Q: Which one do i use for 08 outback xt? (i think amazon was wrong)**
A: I think the 2005-2009 Outback XT's are all the same. The 6 pin white plug is on the left rear under the flooring. It is easy to remove the left floorboard. 

I just three days ago installed the Curt 55370 on my 2006 Outback XT. Its a 'Plug & Play' with no cutting.
