This is slightly off-topic, but I guess somewhat relevant. It's the wiring diagram.

WDS BMW Wiring Diagram System - X5 E70

The sad thing is: the more I know about these cars, the more disillusioned at how many differences there are between the US and rest of the world versions. There's a number of differences in the cornering lights, for example. And in the rest of the world, one can order the Active Seat (massage) for both driver and passenger. In the US/Canada due to the passenger occupancy sensor, this is not possible for the passenger. Grrr!
