I have a 2004 sxt without infinity system. Either after the install or after I disconnected my battery I started getting an airbag light on the dash. I didn't disconnect any wires other than the radio harness, which worked plug and play. I tried disconnecting the neg battery terminal overnight, and currently have the passenger airbag switch apart because the bulb doesn't light when it's switched off. I am getting an ohm reading from where the bulb is soldered to the board, but not sure if this is the correct way to test it. It seems to be okay, any ideas?
