Installed my integrated brake controller myself and son inadvertently bumped the unit while it was disconnected from the dash and the female (red) portion of the comfort System Plug on the back of the unit broke off. I was able to glue it back for now, but I am interested in a more permanent fix. It looks like that part snaps onto the rectangular base and the wore simply plugs in and locks. Can I replace the part of the Plug that is attached to the back of the 8.4 radio system?
