Reply to "Early 1971 (round door handle) fuse pannel"

As you get more familiar with your Pantera, you'll find that substantially zero Panteras match any of the four (4) known wiring diaaagrams published by Ford from '71-75. In addition, the early 71 such as yours were considered "factory prototypes" and had quite a few differences from Ford-imported '71s. Pushbuttons may or may not have been changed or upgraded by other owners or by Ford dealers in the last 31 years. For instance, pushbutton cars originally had both power window switches wired to the same 15-amp fuse; each window motor pulls about 12 amps, so if you touch both switches at once, you'll use a lot of fuses.... What I suggest is to purchase or otherwise acquire a schematic and by trial & error, mark it up to match your particular Pantera. Sorry for such a sketchy answer, but this is a complicated subject.
