I was trying to figure out how to add a trailer brake controller to my 2011 f150 w/o the tow package. I just realized that my wifes 2015 expedition, has the tow package w/o the braker controller. Found plenty of articles about installing the controller on a f150, but nothing for the expedition. Anybody try this yet? I hate to have to rely on what the dealer tells me, as they are usually clueless to these things.
