It goes into the coolant pipe on the passenger side close to the fake firewall under the accordion hose.

Passenger side for sure. Easy to replace.

Nope, driver's side is for the afterrun pump switch

So just to make sure, if we're looking at the engine in the car, the coolant temp. sensor is down below behind the accordian hose and not right behind the top of the y-pipe where the accordian hose connects right? Cuz it looks like there's two sensors there.

there actually is one on the drivers side too, but people always replace the one on the passenger side. don't ask me why, i don't know the difference.

here's the one on the drivers side too. apparently drivers side is for the aux pump, and passenger side is coolant sensor.

Like you said above, the one on the passenger side is the coolant temp sensor (CTS) that actually can affect performance. My car was throwing rich codes and sputtering because mine crapped out. The sensor on the driver side that looks nearly identical to the CTS is the aux pump thermostat which controls when your aux pump runs.
