Thanks to Autozone's online schematic database, it looks like powering the seats should be easy. Apparently there are 6 way and 8 way powered seats on w-bods. So the power wire from the body harness into the seat base will either have an Orange wire into pin A or a Red/White wire into pin A. Ground (Black) is on pin M.
Power door locks is more complex. Can't power up just the switches on the door because all they do is send command signals to the BCM, which probably needs both power AND a happy feeling about who owns the car before it will actuate the door lock solenoids. So I'm still looking for the right schematic that shows the solenoid wires. Will update once I know and will def update if I succeed!
