MG MGF Technical - What is this wire for ?

Can anyone help me on this one. Whilst trying to cure a 'squeaky' seat on my TF160 I noticed a wire with a connector going into the underside of the drivers seat.
Does anyone know what it is it for?

??? seat belt pre-tensioner ???

OR

you may the one TF with an electric chair!!!

Correct john.
It is for the pre-tentioner, it controlls the firing of the explosive.
I think the SRS cables are all yellow?
Kingsley

Explosives !!!
Let me in on this one -- How does the pre-tensioner work ?

IIRC, (and i'll probably be corrected on this)
When the SRS system is activated a charge is set off in the pretentioner which pulls a wire connected to the seat belt clip, as a result this pulls you into the seat.

OK Tim when I next get a peanut stuck in the wind pipe I'll sit in the car and set off the seat belt :-)

In my case only on days with an odd numbered date. On even numbered days like today the SRS lamp is on and the pretensioners not armed. And this is a safety feature?

Thanks Everyone.

Brian, no it's a cost saving feature. if you were to crash the car you wouldn't need to replace the airbags and pretentioners.
These would easily cost a few hundred pounds.;)

And I guess that the airbag at the passengers site will go off no matter if a passenger is present or not.
