Does anyone know where the airbag module is located in an 07 300c?

Staying up all night studying for my exam then leaving my exam headed to work I wrecked my 2007 300c. I have since put it back together. Only thing I need now is to change the airbag module and replace the air bags. Does anyone know the location of the airbag module? I'm thinking is directly on the radio, A sort of yellow box with yellow plugs. Has anyone done this before?
