3-position switch

[boli 996]

I got a 3-postion switch marked I-O-II closed in front of the buttons for the seats memory on drivers side. Any one that knows the function of this switch , the local Porsche dealer didn't have any idea and it doesn't shows in the manual.

The seat heating are placed on the right side at the midle console.

The car is 996 TT-03

Here it comes

Passenger ejector switch.

The switches I usually see just like that, but not in that location, are usually for radar/laser stuff.

That is not a Porsche switch. So what extra do you or did you have wired in the car. Can you even get to that switch with the door closed?

Guesses:

Valet switch for an alarm

Extra lighting

A/C shut off

Cigarette lighter switch for normal/key switch/off

Robocop style shocking alarm system switch

That looks a lot like, exactly, the switch used by some of the aftermarket seat heating kits. Driver's seat OEM, or aftermarket?
