anyone have wiring diagrams for HU harness, lighter, windows

[DmcL]

as above.. im hoping someone will have wiring diagrams for the car side of the headunits wiring harness, the cigarette lighter socket and the window/sunroof switches because im having a problem where when i turn on the headunit or plug anything into the lighter socket i lose power to the windows/sunroof.

suspecting a bad ground, insufficient power supply to the interior electrics or ignition power source.

wanting the diagrams so i can see what wires the power/ignition/grounds are on each of the things mentioned above so i can trace and check them and possibly rewire if necessary.

There are wiring diagrams available for the E30 in the Haynes Manual and the Bentley Manual. The Bentley is a much better manual than the Haynes and the circuit diagrams are easier to follow. It's a worthwhile investment.
