Good luck pulling the airbag connectore withthe seat still bolted down.  It's got a failsafe that makes it a PITA to detach when you can clearly see it, let alone buried under the seat.
There's a green tab that has to slide forward, then a tab in back that actually has to come up in order to detach the bag connector.  Sometimes it takes 2 seconds, sometimes you cusre at the thing for 20 minutes.
Good luck
