I used my PRODIGY II for years until I got my new 2010 Ford truck which had the brake controller built-in.
The FORD BUILT-IN model is totally connected to the FORD Computers and other truck systems and does one thing I hate and makes wish I still was using my PRODIGY.
The FORD Series brake controller are designed not to work with the BRAKE PEDAL when you are under 10MPH speed.
This bothers me when sitting at a stop sign as I would sometimes like to have the trailer brakes engaged especially if I am stopped on a incline.
I have to use the MANUAL SLIDER BAR to keep my trailer brakes active in the situation...
