If the adaptive sports seats are anything like the ones on my Mercedes AMG car, the adjustable bolsters work by inflating the bolsters with air -- there's not just an electrical switch, but also the tube supplying the pressurized air (the problem I sometimes had in one of the AMG seats was the air pressure tube coming unconnected, but that's another story)

 

Thanks, but they made now this adjustable side and shoulder bolsters to work, but I think there was no problem with connection. Hard to desribe for me, since I have no clue in electrician stuff .
