So I replaced the radio on my 99 B300 and the shortly after my air bag light goes off with code 35 which means low resistance in the passenger air bag wiring. When i toke of my radio bezel I discounted the radio, two 12v cigarette outlets and my 4x4 control. I did find a disconnected plastic connector but i believe its suppose to be disconnected because there is a designated spot for it on the bezel where its not connected to anything. Does anyone have a good place for me to look for a disconnected wire? Or a schematic would be helpful.Thanks
