The following is a useful diagnostic for sn95 airbags (particularly 95) from Veryuseful.com. I take no ownership for this content, but thought it would be useful to share. I've used it a TON! Though it may be long, I've always found exactly what I needed in there.

The site nor I take responsibility for the information.
Please take extreme caution when dealing with airbags! If you don't feel comfortable seek a professional.
The site goes over some safety within the article, make sure to read and follow it!
I'll add in;
Disconnect the battery! Then wait a period of time (at least a minute).
When handling an airbag, be aware of its position in the case it does deploy unexpectedly. Not not put your face or body parts in front of the bag. Do no set the bag face down or in a position that if it does deploy it will become a projectile. Even though air bags are relatively inert when un-powered, do not put yourself at risk... They're a powerful device, treat them with respect and caution.
Remember, you cant use the ctrl+f to help find things in there...

Mustang 1995 Air Bag Diagnostic Codes and Debug Information.
Use the information at your own risk. There is no claim to accuracy.
Prolog:
Error code 32 is the most common air bag problem. Chances are Very Good that you have bad clock spring in the steering column. It is Very Easy to replace! Get a NEW one from Ford. They are not very expensive (between ?$45 to $90?). Do NOT waste your time or money getting a used one from the junk yard that may break soon. The clock spring connects the turning steering wheel to your stationary steering column. So, over time, they have a tendency to break.
To replace: just disconnect the battery, yank the air bag, replace the clock spring, put it back together. Get a NEW clock spring from Ford. I think they are still around $70. To remove the air bag,

Air Bag Instructions
WARNING: SERVICE IS MADE BY REPLACEMENT ONLY. DO NOT ATTEMPT SERVICE OF:
AIR BAG MODULES WITH DISCOLORED OR DAMAGED COVER DEPLOYMENT DOORS MUST BE REPLACED, NOT REPAINTED.
NOTE: If ever a part is replaced and the new part did not correct the condition, reinstall the original part and perform the diagnostic procedure again.
WARNING: THE DRIVER AND PASSENGER AIR BAG MODULES WITH DISCOLORED OR DAMAGED TRIM COVER DEPLOYMENT DOORS MUST BE REPLACED, NOT REPAINTED. ANY APPLIED PAINT MAY DAMAGE THE COVER MATERIAL. THIS COULD AFFECT AIR BAG PERFORMANCE DURING DEPLOYMENT AND MAY INCREASE RISK OF INJURY DURING A COLLISION.
NOTE: The instruction "disconnect" always refers to a connector. Never detach a component from the vehicle when instructed to "disconnect." WARNING: VEHICLE SENSOR ORIENTATION IS CRITICAL FOR PROPER SYSTEM OPERATION. IF A VEHICLE EQUIPPED WITH AN AIR BAG SYSTEM IS INVOLVED IN A CRASH WHERE THE FENDERS OR GRILLE AREA HAVE BEEN DAMAGED, INSPECT THE AIR BAG SENSOR MOUNTING BRACKETS FOR DEFORMATION. IF DAMAGED, THE SENSOR SHOULD BE REPLACED WHETHER OR NOT THE AIR BAG IS DEPLOYED. IN ADDITION, ENSURE THAT BODY STRUCTURE IN THE AREA OF SENSOR MOUNTING IS RESTORED TO ITS ORIGINAL CONDITION.
Air Bag Module, Driver Side
NOTE: The driver side air bag module (043B13) is serviced as a complete assembly. Perform proper disposal procedure as outlined.
The driver side air bag module is mounted in the center of the steering wheel (3600). The driver side air bag module consists of the following components:
Inflator
The inflator assembly is not a serviceable item.
Air Bag
The driver side air bag:
A module housing and wheel attaching bracket attach and seal the air bag to the inflator.
Steering Wheel Trim Cover
The steering wheel trim cover:
Air Bag Diagnostic Monitor
The air bag diagnostic monitor (14B056) continually monitors all air bag system components and wiring connections for possible faults when the ignition switch (11572) is in RUN.
Diagnosing Customer Concerns with Hard Diagnostic Trouble Codes
Most air bag system diagnostic procedures will require the use of the System Deactivation and System Reactivation Procedures outlined in this Section. These procedures allow the removal of the driver side air bag module (043B13) and passenger side air bag module (044A74) from the vehicle thereby removing the risk of air bag deployment while diagnostics are performed.
NOTE: The Rotunda Air Bag Simulator 105-00010 for 1995 vehicles has a different connector than previous simulators. The new simulator will only mate with 1993 vehicles and beyond. Likewise, the Rotunda Air Bag Simulator 105-00008 will only mate with 1992 and previous model year vehicles.
Rotunda Air Bag Simulator 105-00010 or equivalent is required to perform diagnosis and testing of the air bag system. The air bag simulator is a 2 ohm resistor used to simulate an air bag connection to the system. It is not acceptable to short circuit the air bag connection with a zero ohm jumper wire. If a zero ohm jumper wire is used to short circuit the air bag connection, an appropriate diagnostic trouble code will be displayed according to the priority scheme.
Deactivation Procedure
Reactivation Procedure
WARNING: THE AIR BAG SIMULATORS MUST BE REMOVED AND THE AIR BAGS RECONNECTED WHEN THE SYSTEM IS REACTIVATED TO AVOID NON-DEPLOYMENT IN A COLLISION RESULTING IN POSSIBLE PERSONAL INJURY.
Glossary
Air Bag Simulator
Rotunda Air Bag Simulator 105-00010 or equivalent is used to simulate air bag connection to system.
Disconnect Component
"DISCONNECT COMPONENT" means disconnect component connector and vehicle harness connector. It does not mean remove component. A disconnected part should not be reconnected unless instructed to do so.
Deactivate System

Prove Out System
"PROVE OUT SYSTEM" means to turn the ignition switch (11572) from OFF to RUN and visually monitor the air bag indicator with the air bags installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag system fault is present, the air bag indicator will either:
The flashing may not occur until approximately 30 seconds after the ignition switch has been turned from OFF to RUN. This is the time required for the air bag diagnostic monitor to complete testing of the air bag system. If the air bag indicator is inoperative and an air bag system fault exists, a tone will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator will need to be serviced before diagnosis can be continued.
Reactivate System
WARNING: THE AIR BAG SIMULATOR MUST BE REMOVED AND THE AIR BAG RECONNECTED WHEN THE SYSTEM IS REACTIVATED TO AVOID NON-DEPLOYMENT IN A COLLISION RESULTING IN POSSIBLE PERSONAL INJURY.

Air Bag Trouble Codes
for Ford Mustangs
Procedure to Retrieve Stored Diagnostic Trouble Codes from Diagnostic Monitor Non-Volatile Random Access Memory
Some Diagnostic Trouble Codes (DTCs) for intermittent problems (61-85) may not automatically flash on the air bag indicator and may require retrieval. If an air bag DTC has been reported on a vehicle but is not currently flashing, this may be due to two reasons:
o A charging system concern has been identified by the diagnostic monitor and a DTC 12 indicated. DTC 12 will not be stored in the air bag diagnostic monitor's Non-Volatile Random Access Memory (NVRAM) under these circumstances. Correction of the charging system problem will eliminate the DTC.
o An intermittent fault has occurred and the fault is no longer present. The diagnostic monitor may be programmed to flash "intermittent" DTCs 61-85 that are stored in NVRAM. Use the following procedure to access the stored DTC(s).
(1) Locate the air bag diagnostic service connector containing Circuit 631 (T/R). This is a grey connector under the glove compartment.
(2) With the ignition key OFF, short Circuit 631 to the ground contained in the service connector or another good ground.
(3) Turn the ignition key to RUN and observe the six second air bag indicator prove-out.
(4) Within two seconds after indicator prove-out, remove the short on Circuit 631.
(5) Stored DTCs will be displayed. After service, repeat steps 1-4 and clean the DTCs cleared using the «DTC Clearing Procedure» .
