The 3 digit prefix denotes the platform (3C0=Passat, 7P6=Toureg, 5K0=Golf6). But usually when the rest of the part number matches, the hardware is actually exactly the same.
I found out the long way that the 9w7 units are not compatible with the R36 steering wheel controls, making them impossible to install and use.
Yes you can get wiring harnesses and mic kits from all over ebay. Doesn't have to specifically be for a 9ZA, 9W7 harness should work fine.
