I feel kind of stupid (and sure show my ignorance) asking the question but
here goes.  My '90 Westy doesn't have/never has had since I've owned it a
'key in' or seat belt buzzer.  I've always just assumed it was pulled or
disabled by the PO.  But I don't even know what or where to look to see what
was done.  I'm assuming (and gather from discussions on the lists) that it
involves a relay w/buzzer? On the fuse block?  If so, what position?  Not
sure I want to replace it, just curious.
