That reminds me of an old trick, where you feed an aux battery into the
fusebox (through one of the back pins), and then replace Fuse3
(radio/clock/int_lights) with a broken one, while using the good one on
the aux+ line.
That way, you could easily switch between aux or main battery on your
acessories, only by swapping the fuses. Good old Harald Holecek (RIP)
came up with this idea.

Unfortunately, I can´t remember the exact pins and layout. Would have to
dig that out somewhere.
