As the owner of a prototype Pantera (all pushbuttons were essentially pre-production prototypes), there were many electrical changes done. There are at least four different wiring schematics available; most of us pick one with a published date near that of our car's mfg date, them annotate it to match our particular machine. A for your fuse problem, there are a few other pushbutton owners in Norway & Sweden. I'd look in the Swedish club's Owners List for someone with an early car (a serial number close to yours- Tomas Gunnarson comes to mind), & do a telephone consultation as to whats working in his car. The other way is to add up the amperage of the components on each circuit and choose a fuse 10% bigger than the total for each circuit. And when one blows with no signs of a defect on the circuit, I'd increase the fuse size slightly.
