So I received my fan switch and thermostat. Problem is I cant find where the fan switch goes. I was told its on the passenger side by the back spark plugs. Maybe if someone had a picture or a way to help me. Its all original so im getting mixed up a bit with all the hoses and wiring. Im also gonna be changing the coolant from anti freeze to distilled water. Every mechanic told me it helps keep it cooler in the summer but in the winter to switch it to antifreeze again.

You won't be able to see if from the top. You need to look from below. It's between the 6 and 8 spark plug area on the passenger side.
