    anyone have wiring diagrams for headunit harness, lighter socket and windows/sunroof?

    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.
