The fastest way is to visit the dealer and hope they will look it up and draw you a diagram. BMW does not release their service information to the public or to the aftermarket service manual providers. They want all the repair business for themselves, and put profits ahead of taking care of their customers. You can also visit one of the many pick-your-own-parts salvage yards and remove a mirror to look at the plug.
