FL A8 seats upgrade

[peiiider]

Hello.

Got a deal off Ebay on a set of sport seats from Germany, matching color with my standard "Swing" interior.

Standard seats have heating, electric seatback and lumbar adjustment in the front, nothing in the back. New seats are fully electric front and heating+lumbar+headrest adjustment in the rear..

Physical installation I guess is no worries, it's the electric part I'm a litte confused about..

Does anybody know the extent of wiring to be installed ? Will ANYTHING fit from old to new at all ? I have access to wiring diagrams through elsa in my garage, but it's a pain going back and forth between the pages of new/old seats to see the differences...plus understanding what is actually inside the seat vs "car wiring"..
