I don't think any of the airbag sensors are in the pillar. They should be connected to other sensors and the bumper and body shocks. If you carefully remove them you will be fine, but may I ask why you would want to take off the A and B pillars?
Actually, the side impact sensors for your side airbags are located on the floor cross members underneath the carpet. A special tool is needed to remove the A-pillar and C-pillar trim...I believe its a T10078.
So do I have to get one of those tools, or will something else work. I was just thinking disconnect the battery and go for it. The reason I am taking it off is to cover it in zebra print. The car is black, and I have the accents in the door already done. I want to do the pillars and the headliner next. I am trying to get them done by the 13th for a car show in Cali.
