I'm not sure I follow you on the airbag part, but if you are asking how to get the wiring into the rig, pop off the cover on the A-pillar and run it down there. There are 5 clips in each side that are going to break when you pop it off so order some from Toyota for a few cents each before you get going. I am running 4 PIAAs up front and 2 in the back and that's how I did it.
