There are dummy load resistors that will make the car's airbag computer think they're okay but as to what resistance and all that I have no clue. Also, for the dumb capacitive airbag occupancy sensor... That's a whole different story. As for parts being removed, usually that shuts down the system and disables it. It won't cause it to go off but I think working safety equipment is pretty important in a car designed to have it.
