E28 Electrical Troubleshooting Manuals (ETM)

ETMs are the go-to resource for tracking down electrical issues in E28s. They appear to only have been printed for US market vehicles, so euro cars may have some minor differences.

E28 Schaltplänes

The Schaltplänes, German for "circuit diagrams", are the BMW factory wiring diagrams. These can be very useful, however they are drawn for a technical audience and not for the faint of heart. We recommend using the ETM unless that doesn't solve your problem.
