OEM BMW E23 7 series wiring diagrams are helpful when diagnosing and troubleshooting electrical issues or wiring electrical components. These are official BMW wiring diagrams and fuse charts from BMW North America. The purpose of the manual is to show electrical schematics in a manner that makes electrical troubleshooting easier. Electrical components which work together are shown together on one schematic.
Switches and other components are represented in such a way that their general layout and function are self explicit. They are arranged on the sheet such that the current path can be followed from positive (top) to negative (bottom)
The components and wires are not drawn to scale. For instance, a lead with a length of over 1m can be shown as a lead that is only a few cm long. To ensure clear arrangement, all connectors, lines branches and connected components from the fuses to the component from the component to ground connection are not shown within the individual cells.
Switches and relays are always shown in the rest position. A component shown in a dashed frame signifies that the component is illustrated only in part. A component shown in a completely drawn frame signifies that the component is illustrated in full.
