I don't have a wiring diagram for a 72 beetle, but on my 71 bus, I had
the same problem. When I turned the key, the brake light and horn fuse
blew instantly. Turned out to be the brake warning switch (screwed into
the master cylinder with two or three wires coming out of it). It was
shorted out. Replacing it fixed the problem. It's cheap... like 7
bucks or something. Do it quick, no need to bleed the brakes, just add
more fluid.
