just put the airbag in a bag and keep it in a safe place. the chances of the airbag blowing up accidentally (when out) are like 0, but there's still a chance.
the steering wheel should have a little part built in and that you can remove. it has a short connector on it. its in red color. if u have that part, then put that on top of the yellow connector coming out of the airbag, and put it some where safe.
its not something to be scared of. like i said the chances of the airbag blowing up by itself are like 0
