O2 Sensor - Only 2 Wires Connected?

Was checking my O2 sensor today and saw that only the two white wires are
plugged into a connector. The black wire has a boot and male flat connector,
but it isn't plugged into anything. The only other unused compatible female
connector is located near the fuel filter toward the firewall. Anybody know
if this is the way it is supposed to be? I thought the whites were for
heating, and the black was for signal?

Eh?
