Hmmm...so simply disconnect all the electrical connectors and that'* it.? Sounds too easy.
Any special tools needed to assist in not breaking anything?

If you take the seat out of the car (I don't think you HAVE to, but it makes it a lot easier), remove the four bolts holding the seat in before disconnecting the electrical connectors because you will need to move the seat forward and backward to access the bolts.

You may need to remove the head rest, to do this you poke a small pointed tool (or a small nail at least 1 inch long) into the small holes at the base of the head rest slides to release the lock tabs, then pull up at the same time. One side at a time.

Be careful not to cut, scratch or scrape things when removing and installing the seat from the car. The metal seat track has very sharp corners and will damage anything it slides up against.

Thats about it, its realy not too hard. And yes, just unplugging the electrical connectors will disable the air bag.

Nothing to worry about with the typcial FSM warning about "static discharge" in removing the seat?

Alright, you'r right Bill, it'* not my car and it not my life so it'* not up to me to tell him how to disable the SIR. Here you go SilverBullet, here is the proper way to disable the SIR system. It'* going to take you a little longer, probably at least another hour if you have never done it before and don't know were the connectors are located.


Disabling the SIR System
Turn the steering wheel so that the vehicle'* wheels are pointing straight ahead.
Turn the ignition switch to the OFF position.
Remove the key from the ignition switch.




Important
With the SIR fuse removed and the ignition switch in the ON position, The AIR BAG warning lamp illuminates. This is normal operation, and does not indicate an SIR system malfunction.


Remove the SIR fuse from the rear fuse block.
Rear fuse block is located under the rear seat.



Remove the driver sound insulator. Refer to Closeout/Insulator Panel Replacement - Left in Instrument Panel, Gauges and Console.
Remove the Connector Position Assurance (CPA) (1) from the driver yellow 2-way connector (3) located next to steering column (2).
Disconnect the driver fontal air bag yellow 2-way connector (4) from the vehicle harness yellow 2-way connector (3).



Remove the passenger sound insulator. Refer to Closeout/Insulator Panel Replacement - Right in Instrument Panel, Gauges and Console.
Remove the Connector Position Assurance (CPA) (4) from the passenger yellow 2-way connector (1) located above the passenger sound insulator.
Disconnect the passenger (IP) fontal air bag yellow 2-way connector (2) from the vehicle harness yellow 2-way connector (1).



Remove the Connector Position Assurance (CPA) from the driver side air bag yellow 2-way connector (4) located under the driver seat.
Disconnect the driver side air bag yellow 2-way connector (1) from the vehicle harness yellow 2-way connector (4).
Remove the Connector Position Assurance (CPA) from the passenger side air bag yellow 2-way connector (4) located under the passenger seat.
Disconnect the passenger side air bag yellow 2-way connector (1) from the vehicle harness yellow 2-way connector (4).

Huh
It is up to you if you know and don't say anything. What a dumb thing to say, man

....but thanks for posting the right way to do it.

I don't understand the rationale for disconnecting the the frontal air bags (driver & passenger). Once you remove the SIR fuse from the rear fuse block, SIR is diabled. You can then disconnect the SIR connector under the drivers seat and be done with it. With the SIR fuse removed there is no power (batt +) to deploy airbags.

On the airbag thing, without hijacking too much.

I'm bringing attention every FSM I've seen goes to great lengths to have you disable the airbags in a specific way for that vehicle. This is because if you unplug it (for example, this one) under the seat, 99% of the time there is no problem at all. However if you catch things just right, you may have a static discharge that sets off the air bag causing damage to the vehicle and possible yourself as well.

Typically you pull the fuse and give the vehicle about an hour, this relieves the power in the module and makes it safe. Seems that the car in question here is a bit more detailed.

Sorry to turn a hour project into much longer. We'd all rather see someone safe.

Correcting myself. After removal of the SIR fuse, there is stored energy in the SDM that takes approximately one minute to dissipate. Additionally, when you disconnect the inflator module under the seat or any of the other 3 inflator modules, a shorting bar closes across the ckt back to the module as an added safety precaution. Bill, I'm not disputing anything that you previously stated. It seems that some of these things are overstated in the FSM.

Well Bill, don't get me wrong I agree it is better to do it the safe way than the fast way, the thing is that the connector he is after has a build in shorting bar that will short the two leads of the air bag module as soon as the connector is unplugged and in turn drain the circuit of any stray energy that may have been in it or may enter after the disconnection.

It is a secondary safety device that GM has used on all the air bag connections for many years now. If a stray spark were to enter into the connector end, it would not have a circuit to complete because the shorting bar has already turned that circuit into a single lead of wire...so it goes nowhere. It'* actually a very good design from a safety stand point.
