Right i've had a look at that diagram you sent to my email, planc, and where the diagram says the sensor should be, there's nothing. I've got my handbrake next to the drivers seat, then an ash tray next to that and behind them both is the junk compartment. Here's a picture to show you.
Was the diagram definitley for a gen 6 1997 GT?
And once again i gotta use photobucket cause it its too big to upload.

Can someone please tell me if there is definitely a sensor inside the car that sets the alarm off if a window breaks or someone's arm comes through an open window.
