I looked this up and about 90% sure this is a water temp sensor, but not sure which to order. It’s on the left side of the thermostat housing, when facing the vehicle. Anyone got the part number by any chance?

I saw that also… that was my 90% certainty part. I think you’re correct it’s the 3FE graph.

Found the part. Putting this here in case anyone runs into this situation in the future
This is a more accurate picture with part numbers.
The water temp sensor is for the ECU.
The water temp sender is for the dash gauge.
The water temp switch tells the ECU when to fire the FPR VSV to control fuel pressure.

And is the “Water Temp Switch” for A/C cutout?
Never mind, I found the answer:
“The water temp switch 89428-60060 tells the ECU when to fire the FPR VSV to control fuel pressure.”
“The water temp switch 89428-60060 tells the ECU when to fire the FPR VSV to control fuel pressure.”
I am not sure the 3FE had an A/C cutout for coolant temp.
There is a feed to the ECU from the AC relay to tell the ECU that the AC clutch is engaged, which pushes the ISC to increase idle speed, but I don't see anything else in that circuit.
From the EWD:
THE CURRENT APPLIED TO THE ENGINE ECU FLOWS THROUGH TERMINAL 7 OF THE
AMPLIFIER ACTIVATING THE ECU TO PREVENT ENGINE SPEED DROP IN A/C OPERATION. THE A/C OPERATION IS SHUT OFF WHEN
A SIGNAL INDICATING LOW EVAPORETOR TEMP., OR ABNORMALLY HIGH OR LOW REFRIGERANT PRESSURE.
WHEN ONE OF THESE SIGNALS IS RECEIVED, THE AMPLIFIER SHUTS OFF THE A/C OPERATION.
Thank you, this is very helpful. It also prompted me to go ahead and order an EWD manual.
