I don't have any for the e39 or the newer model BMWs. Your best bet would be ordering BMW WDS (BMW diagrams CD) or going to the dealer and asking them to buy a wiring diagram booklet for whatever it is that you need it. They are usually split into sections of the car and cost no more than 2-3 dollars a piece.
