An aside to this. A while back when I got a free '91 carat from Uncle Joel
Walker(remember him?) he showed me an aircraft style buss bar with rocker
type resettable circuit breakers that he had installed in the space behind
the glove compartment. It was powered by a cable he had run from the
battery forward. He had added a good bit of electrical stuff to the van and
this took a load off other circuits. Behind the glove box is a good place
for electrical expansion.
