That sounds exactly like an Allison Ignition sensor, and they are
very popular with the MG that run crowd.  Allison may have been
bought by Crane, and there are two big e-mail cos., that sell em,
but for the life of me can't remember there name, ANYONE?.
  At this stage ya gotta get ahold of some that has or sells the
Allison units, I cna't remember any more
Cheers
Bruce
