Checking the wiring diagrams in the bentley ... The contacts 58L and 58R
are not used in the vanagon.
And in 1990 they introduced a switch that has a new contact which is needed
in those model years.
The 58L and 58R are derived inside the fuse panel rather than in the switch.
Looking at 80 to 84 vanagons the second pin 30 was only used as a connect
to get power to the clock and radio (80 to 83) and just the clock in 84.
So after 84 you lost the need for the second 30 terminal. However with the
changes in the amount of current going through that switch over the years I
suspect a beefed up internals was used on the later switches.
