why multiple coolant sensors on L83 engine?
So my 84 has a thermal switch between #6 and #8 plug, but it looks like it's broken or about to break...came off really easy.
But it also has a thermal switch between #1 and #3 plugs.
I have seen conflicting information on where it is supposed to be, but since I only have 1 fan, which one is correct? Does it really matter? I would prefer to disconnect the one on the passanger side and just use the one between #1 and #3 as its easier for me to get to.
With only 1 fan, that isn't controlled by the ECM, does it matter?

I'm not looking at my FSM to give you accurate information on the sensor your asking about but if I were to make a guess I would say that sensor is monitoring temp or pressure to engage the clutch on the A/C compressor.

I have one, but can only find reference to it in the engine electrical section. It shows the one between 1 and 3. I don't know where the other one is, but I'll trace the wiring diagram tomorrow.

There is a fan switch on the '84 Compressor. Maybe these will help. They are from your 1984 manual:

It shouldn't have the same type of connector, the only thing I can think of off the top of my head is the knock sensor connector may be close but I could be wrong.
