Turn signal wire color

I am wiring my euro turn signals and need confirmation about the wire colors.
The car has three wires going to the old turn signals.
brown=ground
Grey=running light?
Blue=turn signal?
I am assuming the above from what I can tell from the poor wiring diagram that I have.
Does this seem correct?

Blaise-
Kinda late, but maybe useful.
Yes, that is correct for the standard BMW wire colors.
Further details-
Left side signals are usually blue w/red marker, right side blue w/black marker.
Left side running lights are usually grey w/yellow marker, right side grey w/white marker.
Brown is ALWAYS ground in German cars, I believe, tho I have never had an Audi or Porsche apart.
Hope this helps!
BTW, if you have US rear lights and want them to be bigger, brighter, and redundant, to help get recognition from other drivers, and for safer driving, let me know- I have a design to double the size and triple the output for under $100, without LEDs, using the unused opportunity BMW left in the US lights. No changes visually, either, and no risk to lenses or wiring.
Good luck with the new turns!
