Find a donor car in a scrapyard and take everything you need. Start from the doors, and chase the cables back to their source. Should be plug in and play, although you may need the relays as mentioned before. A dormant plug will be in your car somewhere. VW would not make one loom for one model, another loom for another mode etc. They all use the same loom, but have different 'add on' looms to fit to the base loom.
