Model s (facelift) Seat features/ control without Hardware unit? -> office chair

[Nick94]

Hi,
I plan to pickup a Model S Facelift seat for a cheap price (around 230USD) to build it as a office chair.
Now i maybe want to use the electric functions like the seat adjustment and maybe also the heating and cooling option.
Is it working with 12v power supply (at least the adjustment) or do i need some controller? or is it only possible with the Tesla main Controller (Hardware Unit?)

Thanks and kind Regards
