map sensor replacement

[T Hergen]

The map from a Chevy '92 S10 4.3L vin W has a 0 - 5v map output.  It is
not like the passive potentiometer of the common GM tps.  It appears to
have some active buffering (likely an op amp).  Resistance measurements
are futile, but it does produce a varying voltage output with vacuum if
you give it gnd and +5v on the appropriate terminals.  The only caveat is
that this particular sensor mounts directly to the intake manifold. 
Depending on your application, you may want one that mounts on the
firewall and has a barb for a vacuum hose.
