o2 sensor wiring
The 2 black wires from the sensor don't matter which is which. The heating element is simply an ungrounded resistor.
Just to expand on what PartsHero said, the yellow/black wire in the car is the 12v power supply for the heater. The orange/black wire goes to the ECU, and the ECU switches the heater on by connecting this to ground.
