Where is the air bag frontal sensor control module located exactly or integrated air bag monitor ?

You Primary Sensor is located under the front Cowling, just below the Hood latch. 
This is the info you need which I retrieved from the ford  tech manual .
Normal Operation 
The normal voltage on pins 2, 6, 17 and 18 is controlled by an internal resistor inside the air bag diagnostic monitor (14B056) and is internally regulated to 10 (± one) volts. The resistance between these pins in the air bag diagnostic monitor connector and ground should be infinite. The resistance across the normally open contacts of the two radiator primary crash front air bag sensors should also be infinite. The air bag diagnostic monitor measures the voltage on pins 2, 6, 17 and 18. If there is any resistance to ground on any of these pins or across the radiator primary crash front air bag sensor contacts, it will cause the diagnostic voltage on these pins to drop below normal levels. If the air bag diagnostic monitor measures a voltage drop to between 5 and 10 volts, the air bag diagnostic monitor senses an internal voltage regulation fault and will flash diagnostic trouble code (DTC) 53. Note that a direct short to ground in the radiator primary crash front air bag sensor circuits will drop the voltage to less than 5 volts, and the air bag diagnostic monitor will flash DTC 14 on the air bag warning indicator (refer to DTC 14 in this section). Also check the "driver side airbag circuit low resistance or shortened"
 It could be a Sensor, Module, or wiring problem. I believe the Crash Sensor is bolted the the Radiator Support of this vehicle.  The Module could be the problem and is under the front of the center console.  There was a Recall on the Module on vehicles built between 9/22/94 and 10/15/94 and at the Hermosillo Assembly Plant.  I would check with a local Ford Dealer, they can check the Vehicle Identification Number and see if this vehicle was effected.
The air bag diagnostic monitor also performs several on-board diagnostics every time the ignition switch is turned to ON. If any of these tests fail, the air bag diagnostic monitor will flash DTC 53 on the air bag warning indicator. 
Possible Causes 
A voltage drop in the radiator primary crash front air bag sensor circuits or an internal air bag diagnostic monitor fault can be caused by: 
A partial drop in voltage in the radiator primary crash front air bag sensor circuits due to resistance to ground on the front air bag sensor wiring or any resistance across the normally open radiator primary crash front air bag sensor contacts. 
Internal air bag diagnostic monitor on-board diagnostic fault. 
Also the procedure to check air bag diagnostic monitor:---
Note: DO NOT ATTEMPT TO DISCONNECT ANY WIRES AT THIS POINT! YOU MAY BLOW YOUR AIRBAG IN YOUR FACE! IT CAN CAUSE SERIOUS INJURY, OR EVEN BE FATAL!
The proper method to view the airbag diagnostic monitor is to remove the console that covers the parking break (2 phillips screws, and a few snap clips, a couple at the rear and couple at the front; but at the front pull straight up), then remove the console that covers the gear shift ( 2 screws, and a couple snap clips), then remove the lower console that is below the ashtray or storage compartment (4 snap clips), then remove the final panels of the console area; there is one on each side (2 snap clips, then pull straight back). 
Once you have removed the final panel, you will be able to view the airbag diagnostic monitor.
The airbag diagnostic monitor in a  ford escort is a "blue" or black box, that sits in a tight compartment near the floor toward the firewall. 
If your vehicle has been through the recall procedure, it will have a plastic cover on the top of it, and the wire connectors on the passenger side will have grease on them.
IF THE AIRBAG DIAGNOSTIC MONITOR DOES "NOT" HAVE A PLASTIC COVER ON TOP OF IT, AND GREASE ON THE WIRES, SCHEDULE A APPOINTMENT WITH YOUR LOCAL FORD DEALER AND HAVE THEM REPAIR IT!
If your vehicle has been through the recall procedure, take the following steps to insure the airbags have not been deployed:
1. FIRST DISCONNECT THE NEGATIVE BATTERY CABLE AND WAIT AT LEAST 1 MINUTE BEFORE THINKING ABOUT DOING ANYTHING ELSE! The airbag diagnostic monitor is designed to hold power for 1 minute after the vehicle power is cut off, and will deploy the airbags if you do not wait.
2. Inspect the airbags. Look for broken plastic, corrosion, burning, or loose connections (It is not necessary to disconnect the wiring to inspect the airbags). Remove the driver air bag by removing the retaining bolts on the back of the steering wheel (2 10mm bolts). Passenger airbag is accessed by opening the glove compartment, pushing the retaining bumpers "in", to drop it down. Passenger airbag is held in by 4 8mm bolts. If you see signs of prior deployment, you will need to replace the air bags, airbag sensors, and the airbag diagnostic monitor. If there are no signs of deployment they should be fine.
3. Remove the wire clips from the airbag diagnostic monitor.
4. Remove the diagnostic monitor retaining bolts (10mm, 2 on driver side, and 1 on passenger side).
5. Slide the diagnostic monitor out.
Make sure you install the recall plastic cover, and put new grease on the wire connections when you install the new monitor. 
Assemble everything in reverse, AND "DO NOT" CONNECT THE BATTERY UNTIL THE REPAIR IS COMPLETE!
