Anyone who tells you to use the B+ for the blue wire should be crossed
off your list of reliable sources. Just look at the Bentley wiring
diagrams, any year, almost any model of VW, alternator section, and see
that the thin blue wire used on virtually every VW since the mid 70s
connects to the D+ of the alternator.

Here is a list of 16 different pages in the Vanagon Bentley where it
shows a blue wire going to alternator terminal D+ !!! Every year and
model and then some.
97.13,  97.20,  97.38,  97.43,  97.56,  97.62,  97.70,  97.87,  97.104,
97.122,  97.204, 97.222,  97.225,  97.32b,  97.33b,  97.34a,

Earlier today I sent you a detailed photo of both versions of Vanagon
waterboxer alternator with a blue wire correctly attached to each. What
on earth more can you need?
