Yes the MY08 D3 pov spec seats are different and sans heater and fandangled ‘lectric movement and also no cover in the front as it has the pull bar for sliding adjustment.
There is one big plastic connector (the type that needs a small bolt to be undone to seperate) under each seat mounted under the torx screw. This can be removed from its mount tab via a spring clip.
Another wire disappears into the seat back. All wires are secured into the base underside with plugs but hard to know their purpose other than weight sensor wire.
Presume those one way plugs pull out with enough force?
Alternative could be to swap covers maybe?
