Just went out to use my 05 international flatbed and I noticed that my brake pressure switch was lite up on the dash. I unplugged the two sensors on the master and it still stays on. I have lots of  brake peddle and changed the fuse and I still can't get the light to go out. I noticed when I touched the brake with the truck off, I don't get that whinny noise motor. Can somebody point  me in the right direction to correct this as I am not a truck mechanic on how to solve this problem...Thanks Paul

Not much help, but check fuses and look for a power problem to the electric motor. I know on ours the light comes on on random start ups, but a quick turn off and on of the ignition and it goes out. We still have the electric motor running when the truck is off though, so I doubt you will be that lucky. I know one of our Topkicks did this quite a few years ago. It ended up being a broken power wire to that electric motor.

Thanks Queensway for the reply. We put a power wire to the motor and the light went out and the brake pedal makes the noise but thats not the fix; if we could just find some schematics on the wiring of this motor and the relays, it would help us out alot. Its hard, none of the dealers want to give up the schematics. See you at the tow show.
