RE: Headlight Switch Later Models
Okay Mark, got that.  Now a follow on question.  Since it appears that a
'90  Vanagon could have either the B or M suffix switches originally (and
corresponding wiring) but either will appear to work correctly (but no fuse
in dash light circuit if B used where M should be) then how does an owner
of a '90 Vanagon check to see which is correct?  This assumes that a PO may
have put in a B where an M was originally.  How can you tell which is the
correct switch?
BTW I'm asking because I think I may have done exactly that some years
back, put in a B when an M failed.
