Find a tach from a diesel Golf or Jetta II, and the tach housing from a
later Vanagon gasser. (I did this in my Syncro TD when I converted it) Mate
the two, and it will fit into the space formerly occupied by the clock. The
signal wire for the tach comes from the 'W' terminal of the alternator. You
will also need a positive and negative to the tach.

The Golf /Jetta tach will have a single opening at the bottom of the face,
so: You may need to use the bottom half of the gasser Vanagon tach face, and
the top half of the Golf / Jetta tach face, mating them together at the
screws that attach the face to the tach unit.

One other alternative I have heard, but not tried, is to use the gasser
Vanagon tach, and there is some sort of signal changer available that will
change the alternator wave signal to a 'square' signal as the gasser tach
needs.
