Barry,
With the unheated sensor all you have to do is connect the voltmeter to
the lead and ground. You might find that a heated sensor is better as it
will stay hot while you are ideling if the sensor isn't located colose to
the engine.
A recent experience with a friends Edlebrock throttle body injection
conversion system that had a heated sensor installed gave a problem when
the heater failed. He was having trouble with it cooling off when he sat
at a stop light.
The heated ones are about $80 bucks but you can probably get one at a
junk yard.
