Subject: Okay READ the subject bar...Hall Effect SPEEDO question.

Hey everyone,
  I need to know how to get a signal for an electronic SPEEDOMETER from a
Hall Effect sender.  I don't see how the signal from a distributor could be
used for anything except a tach.
  Does that little box at the junction of the two part speedomter cable
contain a Hall Effect sender??????????????  If so, how do I get a signal
from it for the speedo? Which terminals do I use?
  thanks in advance
  Mark
