That connects to an inductive sender that signals TDC by generating a
small pulse (from a magnet embedded in the flywheel).  You can see
the other end at the top of the bellhousing.

Used by a VWAG diagnostic tool that's obsolete.  If you have use for
a TDC sensor (only works when the engine is running as the pulse is
proportionate to magnet speed) there it is.  Otherwise it's no use.
