You can do a 7 pin set up with an aftermarket brake controller, not really a big deal, but certainly not as clean as the OEM one.
I doubt I'll need a brake controller on a vehicle with such a low tow weight ability. 3500# is nothing.
The botched launch is ruining future business for Ford. I probably won't bother with Ford after this experience, and I have 4 in my garage at the moment.
