Exclamation Coolant sensor connector wiring

I think my 95 runner w/3vze may have been abducted by aliens. I say this because for some strange reason I cannot locate the wiring/connectors for clnt temp sensor or sender. Also having a 5-speed it, appears I also have a temp switch from an automatic installed. I can just leave this alone correct? after doing cyl head gaskets i thought this would be easier, but i swear i;for the life of me; cannot make these connections. please help. Where would these wires originate from? are they in the main engine management loom? on the throttle body, or egr side? I could use the opportunity to look at another 3vze, but know no one. thx.

Bumpin' for ya.....

Temp switch is fine, but I'll have to look at my wife's 4rnr to give you a good clue for wire locations. I'm pretty sure they're in the main loom/harness, though.

ok, so the aftermarket sensor provided was close to factory replacement. the grooves in the loom connector were not a match to the aftermarket replacement. Turns out, by looking at a friends 3vze at Marlin Crawler, that the incorrect sensor was the culprit all along. go figure. the lesson learned here is, never second guess your photos and notes. thx for your help ;@thook.
