follow the cable to where it goes under the carpet, there will be a socket
and plug, not under the carpet though, where it goes to...

Hello Farang,

If I remember correctly there are maybe three plugs you need to disconnect
and a couple of them may be tough to remove if they have never been
disconnected.  I took both of my front seats out to repair the upholstery
and was pretty surprised that they were as tough to remove and repair as
they were.

Something else you might want to watch out for if you're planning on further
disassembling the seat is to be careful that you don't leave it in the full
back position  because although that position make it easier to unplug
everything, it also covers two bolts that hold the seat bottom to the frame.
