O2 Sensor Help
Could some one tell me what wires do what on my o2 sensor. I have a 89 f150 302. I believe it has three wires. Two white ones and one black on. I know one is for the sensor to communicat with the computer. One is 12v for the heater, and what is the other one a ground for the heater? Wich color goes with each function? Is the black one talk to the computer. While the both white ones are for the heater.?
