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.
