Well joe I can help you with the air bag light. It has to go to a dealer that has the " Star" system diagnostic equipment. It is the only equipment that will turn it off. Now the question is "Why did someone unplug an air bag? You do not want to buy a water damaged car. Let alone salt water damaged car. The electronics will be toast in no time. Hopefully it is the air bag light if you have car inspections in jersey.
