The temperature sensors are the temp2 sensor and the dash panel sensor. The temp2 sender has two channels- one for LH and the other for the EZ unit. Not sure if your model is similar to mine but if it is the temp2 sender is on the passenger side of the bridge and the dash panel sender more to the driver's side.

You do need to know which is which- doubtless some kind soul will advise- that or I will check it out tomorrow for you.

On the two temperature sensors, one has two sensors inside and is called temp2 as Fred said for the engine and ignition systems. The other feeds the temp indicator on the dash. The sensor on the air intake leg is just a switch used to run the electric fan after shutdown (I think).
The temp sensor on the air cleaner box is used by the engine management, but I don't think its a critical component.
The auxiliary air valve has a bimetallic strip inside that slowly closes the valve as it heats up, either from engine heat soak or from a heater coil inside if its still working. It's a slow dumb device for warm up only, it's not an idle control valve like later models that's constantly adjusting the bypass air.
