My 2010 F150 built-in BRAKE CONTROL has many connection to the on-board computers. I like everything it does except one feature.

My BRAKE PEDAL does not engage the OEM brake controller unless the forward speed is above 10MPH I think it is.
What this does that I don't like is engage my trailer brakes when sitting at a stop sign when pushing down on the brake pedal. I like to lock the trailer down so I have to use my thumb switches to engage the brake controller to do it.
I'm sure the guys at ford can track down your problem. Its a great brake controller.
