My Digifant '90 Cabriolet has two wires going to the idle stabilizer.  My Vanagon is Digijet, so I guess I still can't completely answer the question.

Chris,
     Are you saying the the 1990-1991 Vanagon has a
3 wire ISV like the Golf/Jetta Digifant fuel system?
The only Vanagon Digifant fuel system I've ever
seen has a 2 wire ISV?
