I need to find it, and not just the area, I need to know EXACTLY where it is, so I can take it out Today.. Can you help Me, PLEASE..!! Ron

Transmission Control Module (TCM) (LS4)
Left front of the engine compartment, near the left headlight assembly .What engine does your vehicle have ?

LS4
Engine - Gas, 8 CYL, 5.3L, SFI, Aluminum, Cylinder Deactivation, GM

I'm going to take a wild guess an say you have 3.8l

L32
Engine - Gas, 6 Cylinder, 3.8L, SFI, V6 L32
Engine - Gas, 6 Cylinder, 3.8L, SFI, V6 Supercharged, GM
, GM

If it's the 3.8l L32
Engine - Gas, 6 Cylinder, 3.8L, SFI, V6 Supercharged, GM you don't have a TCM module . you have the PCM

other fuses, relays, or ecm faulty.

The Integrated Relay Control Module is located at the RH (passenger side) front of the engine compartment, mounted to the upper radiator support. It controls both power to the PCM (computer) as well as the cooling fans and fuel pump.

I've had the same problem with my 1994 Cougar XR7. It wasn't the module control. It wasn't the fan. It was a bleepin' inline fuse; a 30. Changed the fuse and everything was working fine. That's after I had purchased a new fan motor and electronic control module. None of the book or web pages I have read mentioned that fuse, which for some reason, Ford didn't put in the fuse box with the others. So, check your inline fuse, it may be just that. And it is located past the fuse box under the dash. It'll be the same thing for the T-Bird.

Causes:
- Sensor circuit harness or connectors is open or shorted
- Rear heated oxygen sensor Bank 1 may be faulty
- Fuel pressure may be faulty
- Fuel injector may be faulty
- Intake air leaks

Solution:
Replacing the O2 Sensor 2 usually takes care of the problem.

P0107 - Manifold Absolute Pressure/Barometric Pressure Circuit Low Input
Causes:
- Damage harness or connectors
- MAP sensor circuit is open or shorted
- MAP sensor
- Damaged PCM or ECM

Solutions:
- If damage, repair MAP sensor harness or connector
- Replace MAP sensor

i think that the computer may not be the right one for your car have the supplier check again

It IS on the Passenger side behind the ZGlove box but you may need to Do as they say and remove the Cowl to get to it, Im going to look some more for you on this, as I See you are still Puzzled on it I WILL COOMMENT BACK well I'll keep this open.-------
Ok I just Got it for you its Behind the Passenger Side KICK PANNEL, Where ones RIGHT Foot would Be if Sitting in Pass Seat.

1. Easy job and should have no problems here some help
   Disconnect the negative battery cable.
2. Detach the engine control sensor wiring connector from the ignition control module by pressing down on the locking tab where it is stamped PUSH, and remove the connector.
3. Remove the ignition module and the module bracket from the front fender apron.
4. Unfasten the two ignition module retaining screws, then remove the ignition module form the module bracket.

To install:


Fig. Fig. 2: The ignition module on 1994-95 vehicles is mounted on the front fender apron

1. Install the ignition module onto the module bracket. Tighten the retaining screws to 24-33 inch lbs. (2.7-3.7 Nm).
2. Position the ignition module and bracket assembly onto the front fender apron. Secure with the retaining bolt and tighten to 35-50 inch lbs. (4-5.6 Nm).
3. Attach the engine control sensor wiring connector to the ignition module.
4. Connect the negative battery cable.
   

This sounds as if the (pcm) Powertrain control module has a ground circuit. It will need to be replaced.

This may be your problem.


FORD: 1994-96 THUNDERBIRD LINCOLN-MERCURY: 1994-96 COUGAR ISSUE: Steering efforts at low speeds may intermittently increase to the heavier for highway setting on some vehicles. This is due to electrical "noise" from the Vehicle Speed Sensor (VSS) being picked up by the Electronic Variable Orifice (EVO) module. The EVO module then interprets this as an increase in vehicle speed and reduces the steering assistance to the heavier for highway level.
ACTION: Replace the EVO module with a new module that has improved filtering for electrical noise. Refer to the following Service Procedure for details.
SERVICE PROCEDURE Replace EVO module (F6SZ-3F712-BB). Locations are as follows:

• On 1994-95 vehicles, the EVO module is located under the package tray in the trunk.
• On 1996 vehicles, the EVO is located under the heater blower case on the passenger side.

Refer to Section 11-02 of the appropriate year Thunderbird/Cougar Service Manual for additional diagnosis and repair information.

PART NUMBER PART NAME F6SZ-3F712-BB Electronic Variable Orifice Module OTHER APPLICABLE ARTICLES: NONE
WARRANTY STATUS: Eligible Under The Provisions Of Bumper To Bumper Warranty Coverage
OPERATION DESCRIPTION TIME 960402A Replace Electronic Variable Orifice (EVO) Module - 1994-95 Thunderbird/Cougar 0.5 Hr. 960402B Replace Electronic Variable Orifice (EVO) Module - 1996 Thunderbird/Cougar 0.3 Hr.
