7.3L Power Stroke Engine
The PRO-S Engine Control cable needs to be wired in series with the cab foot
throttle. Use a voltmeter to determine which pins are Idle Validation and Engine Control
Signal.
Idle Validation will be at ground. When the foot pedal is pressed it will rise to 12
VDC.
Engine Control Signal will be 0.6 volts at idle and rise to approximately 3.1 volts
as the foot pedal is pressed.
