Re: Airbag warning light
This seems to be a pretty common issue with the GT
It's usually caused by moving the driver's seat (as you said, this is where the connector is) whilst the ignition is on.
When this originally happened to me, I watched the dealer, and all he did was clean the connector, and use a tie wrap to ensure that it didn't move as much (this is the 'official' fix it seems)
My warning light has come on a couple of times since, but fiddling with the connector under the seat with the ignition off has always fixed it. Check the connector isn't hanging down loose. It should be fastened to the rail under the seat.
