Jeep Wrangler 1995 NP231 Transfer case speed sensor- manual

Resolved Question:

Jeep Wrangler 1995 NP231 Transfer case speed sensor- manual transmission. Unfortunatly someone got to this before me and all the wires from the speed sensor are the same color. I understand one is 5V, one is ground and the other is signal but which is which. How can I check? Is this what they refer to as a " Hall Effect Sensor "?
