Review on 20-Pin Headunit/Radio Wiring Harness for Subaru and Nissan Vehicles with Steering Wheel Switch Wire Compatibility by Matthew Goyette

I used this for a slightly custom project. On older Subaru, you could mount a subwoofer under the seat to give the stereo a fuller sound. With newer cars, they started using custom subwoofers that the owner couldn't easily add. I used it in my fiance's 2010 Forester. Due to differences in pins used on different models, I had to move two wires to get full function of the stock radio. If this suspension were completely filled, it would save time in this regard. Otherwise perfect for my project.
