Also make sure at this point that you have tipped the seat as far forward as it will go, and moved it as far forward as it will go.
Next peel the carpetting away from the back of the car, around the seat belt retracter. The mushroom clips for the carpet is what the material wind deflector hooks onto - they should unscrew by hand (with a bit of persuasion)!!
When you peel it back you will see the seat belt reatracter that needs to be unscrewed. At this point be very careful you don't drop any of the screws (lost 15 mins trying to retrieve a dropped screw!!!)
When it is has been unscrewed, pull it away from the metal and you will see the wiring hole.
