Discussion
Found a Ford document explaining that some Fords use a DC airbag system, some an AC system. The only difference being with the dummy simulator you have to use.
If it's DC, you only need to match the resistance, and if it's AC, you have to match the resistance and capacitance. I think I can guess what we have!
I also read that the trigger of the 'electric match' that sets an airbag off is a current of 1 to 3 amps (for less than 2 milliseconds
) Unfortunately, that's Wikipedia, and as such not the kind of advice I want to gamble on.
It appears Volvos also have an AC airbag system, found somebody who managed to disable them eventually (they made armoured cars and didn't want the airbags or the lights on) but either way, this is going to be a bit of a mission I suspect!
It appears that to trigger the match, you need an appropriate voltage and current, to then provide enough resistive heating to ignite the pyrogen. I don't know enough about the sorts of figures a multimeter puts out to know whether this is going to be pointless looking into.
The 'stand well back' moment would be fairly exciting though I suppose...
Anyway, given that I have a resistor over the connector in the car, surely I could use a meter to find out the voltage going through there? I'm just wondering whether I could find out enough information to make the 'test the airbag in the seats' method feasible? As surely the car itself must have to pass enough current through the airbag to test it without setting it off?
For future reference, I've got an EL-48525 on the way and an EL-46867, which is I think actually for the steering wheel (as I saw one being used for that on some other random forum)
I've got mild hopes for the 48525, as it's a side airbag dummy load. Won't be arriving for a while though!

Naturally I was foiled by Royal Mail. Despite them getting the box and placing it on the desk in front of me, and me having the e-mailed Royal Mail receipt of the paid customs charge, nope, they couldn't let me have it.
Oh well. It eventually arrived, but to my home address instead of work where the card was handed in, so maybe they posted it to the billing address second time round. Who knows.
Second one arrived today, no customs charge as it was by itself fortunately.
Picture for anyone who digs this thread up for reference at some point...
I got mine from a liquidators on ebay, you're supposed to be able to order them from GM, no idea if that'd be allowed if you're just an individual though...

Right, those don't fit the connectors under the seats.
Whilst looking at a lot of the Kent Moore kits, they came with a huge array of cables, so I can only assume that the same air bag dummy load is used on multiple vehicles, and that the different connector types are catered for using intermediary cables or some such treachery.
I'm going to get the dummy load on a meter today to find out the resistance / capacitance etc. and will let people know. Will see if I can't then just solder a couple of wires on to the pins and try jabbing them into the connector under the seat. Hopefully the tiny run of wire won't put the resistance and such outside of the apparently quite strict parameters.

there is potentially another way to turn them off that me and sturdy have been discussing 
Indeed there is Thought I'd let you reveal that, as I've done nothing! 
Needless to say, without that likely lifeline, I'd be a bit more downbeat at this point. Got about 6 weeks until MOT anyway, so got a little time still to play...SturdyHSV said:

might be able to un- program the airbag sensors from the Cluster to stop them showing up. lower spec cars such as a commodore SS use the same clocks but have no side air bags so there is a chance you can turn it ouff for higher models
Did wonder if you'd say that, but wasn't sure if there were also hardware differences. Put me down for it if you manage!KMud said:

Again as a 'for reference' update, the dummy load is 2.2 Ohms.
Capacitance I don't know unfortunately, as we don't have anything suitable for measuring it around the office that I know of...
2.2 Ohms is a standard resistor value - it might be worth just ordering a selection of caps and blindly trying them with a resistor in series.Capacitance I don't know unfortunately, as we don't have anything suitable for measuring it around the office that I know of...

As it has the wrong connector and so won't fit into the plug under the seat, I've turned my dummy load into a snail.
Planning to just jab the wires in, get the code cleared and see if it stays that way. Will then just tape it in place and hopefully it's sorted.
i can clear airbag lights now.... (in theory i have the codes)Planning to just jab the wires in, get the code cleared and see if it stays that way. Will then just tape it in place and hopefully it's sorted.

That's good to hear, may give this a punt anyway to see if it works, although your method does make more sense really...the_ferret82 said:
