Might be the connector for the optional ambiant lighting.
thats a good idea ! i can use that to wire up some ambient lights. do you by chance remember which wires on the connector you tapped into ?It is definitely the auto selector connection for the 5R55 option. I used that to provide the (dimmable) cluster lighting and 12vdc to my dash mounted triple gauge setup on the 2005.
C307 is the connector name in the prints.
ahh okay that makes sense, thanks guys ! definitely wish my 06 came with the ambient lighting though
