Coolant temp sensor location

Crew-cab six cylinder four wheel drive automatic 65,000 miles.

Where is it? It is not around or under the thermostat housing.
I read that it was behind the alternator, looked around the rear and down and did not see it or any wiring heading that way.

Any help would be appreciated.

You are absolutely correct.
The coolant harness was hiding behind two plug wires.

Thank you very much for the information.
