Econoline E550 V8-7.3L DSL Turbo VIN F (2002)
NOTE: The Brake Pressure Applied switch is present on vehicles equipped with speed control.
All vehicles with hydraulic brakes have a single Brake Pressure (BP) switch. An air brake equipped F-650/750 vehicle has two BP switches. A BP
switch provides a backup for the Brake Pedal Position (BPP) switch. Normally, a brakes-applied signal from the BPP switch will disengage the speed
control. If the BPP switch signal is lost, the BP switch will then supply the brakes-applied signal to the speed control servo.
