A question anyone (with a 7A-FE) can answer!, Where does that wire go? Options

To where is the lead from the Oxygen sensor supposed to go?
(It's the 1-wire bolt-in type. )

I searched this forum and elsewhere before posting and found plenty about testing, replacing O2 sensors etc. but all assume the wiring is intact and OK. Would some of you please take a second to pop the hood and take a look. All one needs to do is locate the part and visually trace the wire.

I once saw a photo somewhere in which it seems to go to a connector mounted, I believe, somewhere near the radiator (I have no such connector) but then I also found a diagram that shows it going the opposite direction.

From mine there is several inches of wire to a broken connector and thats it! Coincidentally, I do have another mystery wire that comes from a wrapped bundle nearby that might be its other half but simply connecting them together on a hunch and hoping for the best is something I'd rather not do.

I planned to repair this anyway but now, the pressure's on as I'm not passing the emission test and I think this very well may be (at least, part of) the reason.

I see some of you have already had dealings with your O2 sensor but, for those of you who don't where it is, I've included a few pictures.

The first photo is zoomed out to show the general location; The O2 sensor highlighted in the circle. The second a tighter shot. Both photos taken from standing in front of the engine.

Electrically, I believe it runs to the ECM or first to the data link connector and from there to the ECM but what route does it take to get there?

So, with words or drawings or photograph —whatever works best for you— can someone please tell or show me the path of the oxygen sensor lead.

Thanks!!

It comes from the ECU (plug B pin 6) and splices off under the dash and one wire goes to the DLC and the other goes to the 02 sensor itself.

It runs through the engine wire harness.
