If you want to use an original style, single terminal switch, be aware that the case is the second "contact", since it's grounded to the block. You would have to figure out which of the two leads on the pressure switch is ground, and which is "hot". Then you would run a single wire between the terminal on the new switch and the hot side of the pressure switch.
If you have an old part, you're going to have to figure out exactly what it is, because they aren't all the same. It could be a sensor, which drives a gauge, and would be useless for this application. Or it could be a thermoswitch. If it's a thermoswitch, the temperature set point is important. It may be an 85C switch for the fan, or it could be a cooler switch for the glow plug system. Just because something looks like a fan switch, doesn't mean it will work for your application.
Can't help with the fan.

So camera is acting finicky so ill use some already existing om616 engine bay pics online to help. My engine only has the engine temp sender unit on the drivers side of the cylinder head and the two Allen plugs to the left and right of the temp sender (temp sender unit is in the middle.) So i would remove the front plug and place the new thermo-switch for the fan in there correct?
In the picture shown below you can see the two plugs in the head and make out the temp sender unit wire in the middle, once again sorry for not being able to take my own pictures, but you still get the point. What does the sensor look like that is suppost to go in the cylinder head exactly?
