Im not sure how to wire an o2 sensor I have that is cut and theres no plug except from the motor. Here are the colors and Im not sure what the black black white and green wire goes to. Help me out guys.

 

black - orange black - O2 heater(12v)
black - yellow black - 12v
green - green white - ground
white - white - signal

 

thanks a whole lot.
i was wondering which black goes to what? i did a meter to figure which one to hook it up to right?

 

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.

 

Thanks guys
