Oyviny Custom 4 Pin Trailer Wiring Harness for Select 2009-2024 Subaru Ascent/Crosstrek/Forester/Outback Factory Tow Package Required for Installation, Pure Copper Vehicle-Side 4 Way Trailer Wire

Worked perfectly for my 2017 Subaru Forester, easy installation as well. No instructions with but I found a YouTube video. Whole process around 5 minutes

2017 crosstrek works perfectly, and install was simple.

Attaches to the Subaru connections without altering. Only downside is that the flat four prong plugs aren’t durable.

Easily installed or removed with no damage to original wiring. And, works perfectly.

The part was really easy to install and it was just what we needed to hook up to the trailer. Worked like a charm.

My towing light wasn't working properly. After trying some diagnostics, I determined the conversion box was defective. I happened to find this item on Amazon. I own a 2014 Subaru Forester, and this set up was perfect. The plug and play concept saved splicing each wire. I tow a small utility trailer and have extra 12-volt taillights on a hitch mount bike rack for additional safety. Everything's working as it should. Glad I saw this. Probably saved some $$$$ by doing it myself. It took more time taking things out and in than it did installing the new harness.

Installed this in less than 5 mins on my 2023 Subaru outback Wilderness. Literally plug and play with the harness that Subaru already has on the car under the trunk trim piece.

Works great! Price was right. Bought this to keep my Prius Prime start battery charged when I am away for extended vacation. Just tested it on my motor home battery before I leave . Brought it to full charge is 2 days & holding 12.79 volts. Very pleased.
