multi-function temp sensor

[Ed Kellock <EKELLOCK@ecs-inc.com>]

I know this has been covered before.  Just got a new multi-function temp
sensor for the 91 200qw and it's a three-pronger.  I remember posts
about this being a superceding part.

Can anyone refresh my memory of this issue?  Does this also apply to the
3B engine?  
Bought from Linda @ Carlsen.  Made sure she realized it was for a 3B.
She said they're all the same.

TIA.
