Hi. I have a question/problem that the forum told me you may be able to help me out. I installed the integrated brake controller on 2012, 1500 sport. I only had plug "a". I wired plug "b" as per instructions on the forum. Took it to dealer had them flash it. Now when I connect to trailer, the trailer locks-up and won't roll. Frontwards or backwards. I have set the controller to 0.0 but it still locks up. Is there another setting that I can set it at or did I get a wire reversed?
Any help would be great.
