Mr Damage : ( I like that..!! ) do a simple test , step off the car ( please , not while moving specially at speed )on a flat surface and start the car , with your hand press on the seat where your right leg would normally be .. IF you can get the light/chime to make you say "bugger" then you have a good chance that the harness that goes from the under the carpet ,you will see the ends when you look under the seat , that harness goes to the air bag .Chrysler may charge you ~$60 to change it.. there is a few past posts about this subject.

ps I still have the old harness that I repaired before I changed it .the wires crease in that spot.
