What color is the O2 sensor wire that goes to the computer?



In my 1999 Jeep Cherokee, with a 4.0L inline 6, I need to find the color of the wiring harness wire from the pre-catalytic convertor oxygen sensor. Does anyone know? I think it’s the black with dark green strip, but I have found conflicting information on the internet and in my Haynes book.



My sources show that the light green/red wire is the signal out wire from the O2 sensor.



Thanks Tester. Can I ask what your sources are? I have never seen that color combo as the signal.
This is the pre-cat sensor.

Black/Dark Green wire is signal out to the computer.
