EXACT LOCATION AND DESCRIPTION OF THE ANTI THEFT MODULE ON A 1998/1999 FORD WINDSTAR
Section 13-11: Anti-Theft System, Active

DESCRIPTION AND OPERATION
Anti-Theft Alarm System
NOTE: The system immediately monitors the ignition key lock cylinder upon removal of the key from the ignition. It is not necessary to arm the system for ignition key lock monitoring.
The anti-theft alarm system:
Once triggered, the system responds by:

Components
The system is composed of the following components:
The following vehicle components are also used by the anti-theft alarm system:

Disarming an Untriggered System
NOTE: A perimeter alarm will "shut off" after 165 seconds, but the system is still triggered and is not disarmed.
An armed but untriggered perimeter anti-theft system can be disarmed by one of the following four events:
------------------------------------------------
System Triggering
NOTE: Although the remote entry PANIC alarm is not associated with the monitoring of the vehicle, the user will frequently say that the theft system was triggered when actually the keyless entry remote transmitter PANIC button was inadvertently pressed. A panic alarm will not flash the THEFT indicator.
The alarm can be triggered by the following events if the system has been armed and has not been disarmed first:
When the system is triggered the perimeter alarm will operate as follows:
The remote anti-theft personality module will pulse the following outputs at approximately 1.3 Hz, 50 percent duty cycle for two minutes 45 seconds for North America.
NOTE: Other perimeter alarms can be programmed for the system.
The perimeter alarm can be retriggered, after a perimeter alarm has sounded for 165 seconds. After a perimeter alarm has timed out, if any trigger input is first seen as normal and is then seen in its trigger state, the perimeter alarm will be retriggered. The perimeter alarm can be triggered a total of three times between an arming sequence and a disarm event. An active panic alarm will be deactivated when a perimeter alarm is triggered (a perimeter alarm overrides a panic alarm).
SOURCE: EXACT LOCATION AND DESCRIPTION OF THE ANTI THEFT
there is no separate anti theft module, it is part of the PCM which is the main computer in the van that runs the engine and emission system as well as the PATS (Passive Anti Theft)
Tell me your problem and perhaps I can give u and answer, I am a Ford Factory Technician.

ITS THE FIRST CONFIGURATION ( CANNOT CRANK THE ENGINE OVER)
HOW MAY I BYPASS/REPAIR THIS TROUBLESOME PROBLEM, AND GET THE USE OF MY CAR BACK FROM MY GIRLFRIEND?
OH YES, THE IGNITION KEY ISNT DAMAGED THAT I CAN SEE.
Ford passive anti-theft Systems (PATS) come in two configurations. The first takes away the ability to crank the engine over, using a starter interrupt relay to control the starter relay. The second configuration allows the engine to crank, but takes the fuel injector pulse away. Some systems use a separate anti-theft module, while others are incorporated into the powertrain control module (PCM) or instrument cluster. All PATS systems use a chip in the large black plastic end of the key to trigger a start. The chip is under a small square plug in the key. If there is a hole there, the chip has fallen out.
