hope this can help you. I didnt find one with speakers wires but it should be easy to figure. just look to see what color wires conect to the speakers,

A voltmeter will work wonders.

Hey, J.A.C, where did this diagram come from?
I need to track down a copy to get into my doors, cargo, dome light, etc.

A Chilton or Haynes manual from your local auto parts store will have diagrams in it (along with a wealth of other useful info).

Yes, but their diagrams don't include the door switches, dome or cargo lights.
