The schematic for a BSM B3 switch is straightforward, as it is an electromechanical device. However, the internal architecture is designed for high precision.

: Unlike Delphi units where the fuel pump relay rests in an accessible slot directly above the black connector, Siemens maps this internally, requiring board-level tracing if a failure occurs. 4. Common Point-of-Failure Diagnostics siemens bsm b3 schematic

If you have the motor nameplate, head to the Siemens Industry Online Support site. You are generally looking for documentation in the catalog, often under manual code D 21.1 or similar.
