I'm in canada and when I build an ascent online at subaru.ca it says the price for the hitch and states it does not include installation. I need it for 5000 Lb towing with the 7 pin trailer wiring connector. I will install my own brake controller for my trailer brakes. Does the hitch come with the 7 pin connector? and does anyone know what the total cost incl installation of all parts is to tow 5000 Lbs? Also they don't mention if a transmission cooler is required and if so I wonder what the total cost is for this as well. Just trying to figure out what the total would be for everything so I can drive off and tow. Except the brake controller of course... on that note I assume there is a wiring harness for the brake controller near the dash somewhere that I can just plug into like the pilot has?
