Wiring help from the driver's side
 

I'm having issues finding out where these wires go.

Where does this plug to? Or what is it for?:

I also need help identifying these 3 wires, theyre all on the same harness the starter is on.

1 is blue with a yellowish/white wire
2 is a black wire with red stripe
3 is a brown wire with a white stripe

Thanks in advance!

Factory Service Manual is your friend.

Top pic is the other end of the wire for the low coolant sensor.

Black with Red goes to A/C compressor
Brown with white goes to the connector in your first pic.
Blue with yellow goes to power steering pump.
