I'll update later regrading the wiring. I'll have to check both of mine.

I did want to thank you both for the info. It confirms that I need to take an extra step to get this to work the right way. I'm assesing how to proceed. I'm thinking I may try to modify one car and buy a UK lamp assembly for the other, then compare.

FYI. In my research, I found the following VAG part numbers. I'm missing the PN for the correct oem VAG "repair wire" to use that will fit the connector and the terminals to the bulb socket. Whenever I find it, I'll post that, too.

Fog lamp bulb socket: 893945265
Connector to lamp socket: 443971996
