Nice summary Bill. One thing to add. If you have a 2006, you'll also need to make a change in vagcom in order to have the rings as your tails on the outers.
BYTE 09 Center of Tails.
Normal = HEX 0A.
Set BYTE 09 to HEX 00.
Euro = vagcom change
US 2007-2011 = snip black wire
US 2006 = vagcom change AND snip black wire.
edit: I just saw you have a 2006. Did you not have to make the vagcom change? I thought we had determined on the other thread that the 06's need both changes. Mine did.
