Re: srs light
That's like saying "I'm getting a check engine light and I don't know why. The engine is where it's supposed to be".
There are sensors and controllers for the SRS system, and harnesses. Just having the airbags plugged in is only a small part of the overall system. Try resetting the light first, and if that doesn't work then see if there is any way to flash out the SRS codes for your particular car.
