I recently put a low millage 2.3l in my ranger. I was unaware that the person who removed the motor that I purchased had not disconnected the O2 sensor after the cat. So I have a harness with no downstream O2 sensor wires because they were torn away from the harness.

The motor is in the truck and runs great but I would like to get it all squared away. Also, I have not been able to locate where the wires were torn away from the harness.

HOW can I re-wire the second sensor? Also is it in line, or wired together with the sensor before the catalytic converter in any away?

THANK YOU IN ADVANCE!
 
well, once you find where it wires in, you shouldnt have a problem adding it. best of luck with it though.
