IIRC the light usually resets itself when the fault is fixed (ie airbag replaced or a resistor put in its place. I know a 5 amp blade fuse is the usual resistor that most companies supply with steering wheel boss units, but the tensioner plugs would require a different resistor. you could use different fuses to try it till light goes out if you were bothered, alternatively dont worry about the light at all and when you put your std seats back, the light should go out when seat tensioners are plugged in.
