Wrong Temperature Sensor? 1995 Explorer EFI OHV 4.0L

So I went to the auto parts and bought a temperature sensor sender, all fine and dandy till I arrived home and tried to replace it, and it wasn't exactly what I was trying to buy.

I'm guessing this is the Engine Temperature Sensor and not the Temperature Sender Unit, right?

Anyway since I got this already and it was cheap I may as well use it.
But I can't exactly locate where this goes. I know the one to the top left above the thermostat housing is the unit sender(I think so).

Any help locating where this goes will be appreciated.

I tried using google and more but I just get mixed results.

Alright. This is the unit sender, right?

Temperature Sensor is the one to the right?

IF I'm right let me put some tags so it will be easy for people to search for it while using google.

I used to work at an auto parts store and most customers asked for the wrong part. There is a temp SENDER (works the temp gauge) and a coolant temp SENSOR (tells the PCM the engine's temp and increases the amount of fuel delivered during cold start-up (if necessary) by increasing the fuel injector pulse width, like an automatic choke on a carbureted engine. If I remember correctly, not all Ford coolant temp SENSORS have 2 wires (some have only 1). The way I told them apart, visually, was that the gauge SENDER had a cylindrical tip and the coolant temp SENSOR had a wider conical shaped tip. Sometimes the sender is found in the cylinder head and sometimes it's in the intake manifold or the thermostat housing, but they are always placed in the coolant stream.

I reject your reality & substitute my own...
