There are 2 places I would use to get 12 volts in a waterboxer engine
compartment. The 13mm wiring nut on the alternator has a direct
connection to the battery. Another and better protected spot is inside
the black box on the driver's side front edge of the compartment. There
is a metal stud inside with a few red wires to it. This stud always has
12 volts to it as one of the red wires comes from the previously
mentioned 13mm nut on the alternator. No matter what, use a properly
sized fuse placed very near to the source you pick if you plan to leave
a wire connected.
