Hello there,
  In reassembling my dash after doing the blower motor and headlamp
relays on my '84 1.9L I discovered an orphaned connector that I can't
recall if was connected to anything or originally alone.

It's a black wire with a single male spade in a VW plastic plug/housing
(p/n 161 971 976), the wire come off the fuse box on the end closest to
the steering column.  It orginates on a 2 fuse panel to the right of my
row of relays, ie not with the rest of the regular fuses.  The wire
splits off from a green wire with a yellow stripe (if memory serves me
correctly) that connects to the rear heater switch in the dash.

Thanks!
  Tolga
