Here is a page that goes into building a test box for a non-VW gauge.
Example is a fuel gauge and the resistances differ from Vanagon but the
principle is the same.  I did this to a similar gauge but just wired up
groups of resistors for a 1-time calibration rather than build the box
-- worked fine.  Like John sez -- just a couple of bucks to set up the test.
