Coolant temp sensor and engine temp sensor

[aronmigz]

I can't seem to find the coolant temp sensor or te engine temp sensor/senders on my 88 pickup 22r carbed.
I found 2 sensors located infront the carb behind the water inlet on the engine.
But the sensor I got from autozone has 2 prongs the one on the engine has one prong connectors. So I'm kinda lost now :/
