Yes, I stand corrected.  I meant to say the third terminal has no function for my '87.

Not quite accurate. The 3 terminal brake light switch was stock for
80-84 vans and those used the 3rd terminal has part of a hydraulic
system failure warning. So the 3 pin switch did not replace the 2 pin,
it is the other way around. The 2 pin is the later switch version. VW
deleted the hydraulic failure warning beginning with 85 vans and added a
fluid level switch to the brake reservoir cap instead.

Peter knows this of course.
