I am hoping that someone can advise me about where to find the trailer wiring plug on my 2013. I just put on a hitch and I have the wiring, but I can't find the plug where I read it is supposed to be. I installed hitches and wiring on 04 and 08 outbacks with no problem, and I was able to reach in by the inside of the driver's side fender and there it was. From what I had read that is how this car is supposed to be, but I can't find one. There is a 12V 120W outlet on the driver's side higher up. There is a wire that comes in or goes out through the metal fender near where I would expect the trailer wiring to be, but it runs up and joins a larger wiring harness just below the rear window. I can't take a picture, I don't how to remove the inner plastic wall in the trunk so I am doing this all by pulling it away at the bottom and reaching up in there. I also felt around on the passenger side but I couldn't feel any wiring over there. If anyone can help me with what to do next I will be very grateful, as I am stumped. Thank you very much.
