There should not be any issues. Had heated seats and electric before - just remove the wiring or disconnect if you ever want to put the old ones back in

firstly make sure the car is turned off and the key is nowhere near the car while you are doing this. do not turn it on until you are totally finished or else the airbag light will trip and you will have to go to the OPC to have it reset.

the only important part to note is to make sure that you separate the seatbelt recepticle wiring plug from the block connector on the seat wiring harness and plug it back in to the chassis harness under the seat when you instal the new seats. the airbag ecu needs to read these as being connected or you get the issue mentioned above.

everything else is straightforward. any electric gizmos you had on the seat will now just no longer be there.
if you have memory mirrors these will now no longer function, though the electric mirror will still work.

Just drivers, otherwise light would be on when you drive on your own with nobody in the passenger seat.

For most cars there's an "occupancy sensor" in the passenger seat, which will activate the seatbelt warning light if appropriate and also the airbag if there's an impact. I'm surprised 996s are different, but I guess if there's no wiring there they must be.

Thinking about it there is wiring for the seat electrics (sport seats) but no light on the dash if passenger doesn't have the belt on.

That's from memory and I might be corrected on this or maybe it altered on different MY.

No issues as long as you are using existing Seat Belt on the seat (that is the only light that will pop up)

I used this guide to help me fit buckets into my GT3, it shows the wiring that is needed:

there should be wiring on both seat belt recepticles.
it runs to the block type multiconnector under the seat. you not only need to split these to get the seat out but you then need to dismantle the connector attached to the seat to split out just the wiring for the seat belt.

you can see this in the images in the link posted above.

defo no wire on the passenger side if you are looking on the internet on a us website there wiring is diffrent as i think all there cars have seatbelt buzzers or some anoying sound

I don't think you will have any problems with the airbag. On UK cars, the belt buckle on the driver's side is only connected to the instrument cluster, for the 'belt undone' warning message. There is no connection to the passenger buckle.

It is only USA cars which have the buckle connected to the airbag control unit.
