I have a 1986 Ford Ranger and have just purchased an AutoMeter Air/Fuel

mixture guage and cannot find the signal wire on my O2 sensor. On the sensor

itself it has three wires one black and two white, and on the harness it has one

yellow, and either two green or one green and one black, I cant tell light wasnt

brite. Can anyone tell me which one to splice into, I dont want to make a

mistake and fry the sensor or my 60 dollar guage. Please reply soon to my e

mail, (Click Here to find out why email addresses are removed from posts.). Thank you.
