Created during the production of the original Shop Manual, BMW produced electronic copies of the original electrical diagrams. These are not easy to find any more. BMW has not produced an updated electronic copy of the shop manual that you can run on anything but Windows 95-98 unfortunately.
These are the PDFs created scanned from the original artwork, for the original CD-Rom.
