Actually, on Vanagons very little of the power needed for running the
engine runs through the ignition switch. Most of the power needed for
the engine while it is running comes from the alternator right to the
fuel injection system wiring and with no fuses involved.

In Vanagons the ignition switch powers on the ignition coil. It also
turns on the power relays in the engine compartment. The exact details
varied over the years.
