You don't even have to do that. At least on the ones on the steering wheel there is a yellow wire that runs down the column with a connector underneath the knee panel. Then there's another connector on the back of the airbag once you get it off the wheel. You just want to ground yourself before you handle it, at least if it's very dry. For years I disconnected them without a grounding strap but I don't do it anymore. If I made a list of all the things I did when I was young and dumb that I wouldn't do now there wouldn't be enough paper in the world to write it on. Anyway, you have an ordnance in your hand once you disconnect it from the steering wheel and enough static electricity can make the thing deploy
