Ok, first of all, Hi!! Just joined recently, and there is soooo much information here, it's easy to get lost. So, I'm just gonna ask....I have a 2017 XLT Ecoboost. I just bought a 31ft, 5600 lb dry wt camper. My Expy does have the brake module plug behind the cubby, and the 4 pin trailer connection with the 5th wire tied to it. I can add/convert the trailer plug to 7 pin myself. As far as the brake module....... Should I attempt the process of doing it myself, or just let the dealership handle it?
