It could be that yours has a similar problem, so even when the pressure differential valve moves just a tiny bit, the pin moves up and closes the switch.

I will check that out - Im not sure why it didnt register to me when you first said it but I will try that. Maybe as simple as a switch. Since I am away from the truck and havent tried the pedal with it running - should be pedal be harder/more firm with the booster set up when the motor is running? Or softer? Like I said I havent run it, and last I drove this truck it was manual brakes.
