Airbag light after fitting coilovers?
 

Hi all.

I recently fitted some coilovers to my 54 plate wrx. When I drove the car out of the garage I noticed the airbag light had come on :cry:

There was a little black box behind the rear seats, I don't know what this is, or where it's supposed to sit, but could it be anything to do with this??

Any help appreciated. Thanks.
