2.3L ('83-'97) O2 sensor wire help

[ThatOneGuy]

It's been several years since I've been around last week I bought an 83 2.3 4x4. Been doing some work to her I noticed the 0s has the wire cut at the sensor. Plan to replace next week but I cant seem to find where it would plug into the harness any help appreciated.

An 83 shouldn't have o2 sensors. Carburetors tend to run fine without them...

That's what I thought but it's right there just below the exhaust manifold. Could it have come from a later engine oh well figured it had to of been pluged into something at some point.

Probably like you said, a later model exhaust pipe and they just stuck an o2 sensor in to plug the hole...
