This was a piece of cake to install. Finding the connector on the Subaru took a few minutes. The easiest way is to just follow the wiring harness crossing the back near the tire well. I was not real impressed by the lack of protection for the wiring outside of the vehicle. I opted to run it inside some flexible accordian tubing and seal it up to protect it over time much better. It also makes the installation appear much neater. Be sure to use a few more tie-raps so it doesn't get caught up in the spare tire down the road.
