It is under Settings, then Driver Assist... it is with the rear parking aid and trailer sway control.

I posted a question on one of the Ford Truck sites I'm on because actually I don't know what's the difference other than I go into the settings and change them depending on the trailer I am pulling. If anyone posts some good information I'll pass it along.

What system did you go with? I have pulled with two different ones now and noticed with my Carlisle set up sometimes didn't give the braking power when I had to get on them hard and fast. Now the current system doesn't seem to grab as hard instantaneous with the truck, but once it does you know it!

I have a Titan pump. It seems to match the truck's braking very well. But yes, when you need to stand on it, it really grabs hard.
