    Need "schematic", NOT "wiring diagram" for Bose HU - 2001 Eldorado - part #09354806.

    Hey folks,

    Any chance that anyone has, or knows where I can get a schematic for a Bose head unit from a 2001 Eldorado - manufacturer part #09354806? I'm looking for the schematic, not the wiring diagram, to trace down some chips/parts on the mainboard/circuit board for the cassette player section.

    Specifically, I'm looking for the tape preamp circuit output so that I can tap into it to use as an aux audio input. If you plug in a line level signal "before" the preamp (which is designed for the low-level signal from the tape head), you won't get a good result. But tap into the "Tape" source circuit "after" the tape (magnetic head) preamp, and the rest of the amp circuit will accept the signal and you can play it through the Bose system.

    (I haven't taken the unit apart yet; it might be easy to trace the circuit without a schematic. But figured I check here first to possibly save some time.)

    Thanks much.
