What year is your Superduty? If it is of the years that had an available factory integrated brake controller, I would recommend going that route. My '11 F150 has one, and it is the way to go IMO. I don't know off the top of my head the years they were available, but I think I recall seeing them in Superduty trucks as far back as 2005.
Good luck!

also you need to have a charged 12 volt battery on your trailer connected to the break away cable- switch for it work
