With my new X I got the little pigtail that is supposed to be used to connect up a trailer brake controller. I got all the cabling in place. But pulling the carpet back and exposing the connectors, kind of up behind the OBD connector, I can not find where the the heck the mating connector is supposed to go. Does anyone have an idea where the brake controller is supposed to go? Of course it Friday night and the SC is closed. Nuts!
