Whilst I was in Europe I was given a cd dated 07-07 with all the BMW wiring diagrams for current models.
They are somewhat cryptic (some components appear in several diagrams) but are in PDF format. They also some include details of the connectors (i.e. plugs and sockets). However, information about 6FL is somewhat limited (probably because it was a recent introduction back then).
Let me know if you need anything specific and I will see what I can do to let you have the diagrams.
