Thanks guys, now can anyone tell me what sensor would the one from the third pic be? And the brown wire from the second picture goes to?
 
There are three sensors that are screwed into your thermostat housing. In the lower housing: one is the coolant temp sensor (for the ECU)- it has a connector that has two perpendicular spades (towards the passenger side), and the temp sending unit (for the dash) has a one spade connector and is on the driver side. In the upper housing, you have the ac switch.

Last Pic:
The big one is the temp sensor for the ecu (perpendicular spades)
The small (one spade connector)is the temp sensor for the temp gauge in the dash

Third Pic:
The sensor is for the AC switch
 
the first picture shows all the wires that aren't connected, i think i just figured out most of them except for the brown one from the second picture. All the wires come from the same harness of where the o2 sensor connector, coolant wires, as well as the wires from the injectors. As you can see in the second picture, it seems that the previous owner added a piece of brown wire to the naked wire that is coming out of harness
