Well, that is a quite simple task for all pre-2013 Z4:
  • open the flat plate of the old housing with a tiny screwdriver and don't tear it off!
  • unpin the 2 pins out of the old housing sorrowly without damaging the housing
  • cut the new oval housing several times deeply and bend it out like a flower (really!)
  • remove the pink plate to be able to unpin the 2 new pins
  • pull out the 2 new pins
  • turn off the green gummis
  • re-crimp each pin with a good AWG20-22 crimp tool
  • pin the 2 new pins into the old housing
This takes about 2 minutes per switch and is much easier than re-soldering or fiddling around with an expensive adapter, that BMW offers.

Just do it and don't wait two long if you won't run into troubles while driving even with an already closed(!) roof.
