Possible Electric Blind Retrofit

[steamship]

Would like to retrofit the rear blinds to my 01 FL D2 as it's something I can afford to do. The issue is I can't find a guide anywhere on how to retrofit them, other than partial references to it when carrying out other work. I've had a look on eBay and reckon I can source most/all of the bits from A8parts, but need to make sure that I get everything I need. Apart from the obvious rear parcel shelf with blind, the two door cards with blinds, clips for the door blinds and a switch for the dash, what else do I need? I've come across a 'rear blind control unit', which I assume is required. Any other parts required? What about wiring? Is there much involved? Any help on providing a list of parts or a rough idea of what's involved would be much appreciated.
