I've just installed my projectors and hids today on a 200. It took about 3 hours in total. I followed the guide on how to take the bumper off and it was fairly easy.
The projector lamp is H1, the main and turning/cornering are H7. The turning lamp will not work due to the lack of wiring on the loom. I just put a spare H7 in which was left over from my reflector lights.
