Several air bags in the car, a connector on every one of them. Several other electronic components are part of the air bag system, connector on every one of those too. What connector are you looking for? Or (taking a step back), why? The wiring diagram shows them all, where in the car they're located, their shapes, etc.
Oh, so you're looking for the car's diagnostic connector so you can connect a code reader and find out why? That's under the dash on the driver's side, more or less above where your knees go.
