Electric doors?? Are you talking about door locks? If so, even though they are electric, you can still operate them manually. Disconnect the power to the door locks and they are then manual.
You can get a wiring diagram for electric windows on a GMC Vandura 2500 in the owner's manual. You can also find it at various auto stores.
