That entire harness is powered from the 30 terminal post in the
wiring box on the firewall (for people following the regulator
external sensing thread, it's the wire that needs to be removed from
there and fed instead from a source that's not between the alternator
and the battery).

It seems more than likely that the P/S pressure switch lead was
involved (very "clever," they're feeding a signal input straight from
the ECU relay output) since that lead was burnt clear to the
switch.  How or what it shorted to is a mystery to me.

The Vanagon Guardian Angel saved my butt by having this happen 0.82
miles after a 700 mile trip and six days before a 1500 mile trip, and
only charged me the cost of a harness for the lesson that fusing the
30 lead is like a tetanus shot -- it's not likely to be needed, but
the consequences if you need it and don't have it are dreadful.  And
it's not as though I didn't know about it, just didn't have a round
tuit.  Well I got one, stuck where the sun don't shine.
