Trailer brake OEM wiring

[jurassicman]

Subaru 2019 Ascent with OEM trailer hitch: Does the Ascent have wiring from the driver brake area to the round trailer hitch receptacle (7 pins I think) to support a trailer braking Controller? i.e. connector somewhere under the dash to pin 2 of the Round Trailer Hitch receptacle.

My 2020 Ascent had great wiring and explanations so I could install my own choice of trailer connector and braking controller. It's a lot of work. I installed my own hitch as well. You have to take off all of the lower rear body to get to the stuff. The rear harness has a place to add a towing harness. That towing harness has a box that prevents the trailer from draining the battery. Up in the front there is a harness connection for a braking controller. I got the hitch and harness from etrailer.com. Thats probably the best place to get the brake controller as well. I would not recommend the one I ended up with. I went cheap and regretted it.
