Well, with the good responses to my initial statement I'd better modify it
to say "You better know what your dealing with if you want to shorten or
extend the leads on the sensor".  Sounds like what I thought was sound
advice was correct for only very limited situations.  So thanks for the
better (and much more complete) answers.
