Air bag disarming while fitting alarm

I'm about to wire an alarm with imobilizer into the mx but am a bit nervous about the airbags. I've never worked on the electrics of a car with airbags and am a bit nervous about accidentally deploying them. Does anyone know how to temporarily disable them. Ive seen on one forum a suggestion to disconnect the battery and wait 30 mins but I've also heard that they may retain some residual charge and can still deploy ????

Disconnect battery and turn the headlights on. Any stored residual is soaked up by the headlight circuit,

That's what Richard Larsson from MX5 Plus told me when I replaced the steering wheel - I tend to do this for all electrical work on the car now as a habit.
