How do i install this thing and where would i find it on the car
The O2 sensor goes in the exhaust pipe just below the exhaust manifold. That model may have an O2 sensor on each side of the engine, but they should be the only thing screwed into the exhaust pipe. And I would use TOYOTA brand parts or, if you have to replace it again,(and you probably would), you may have trouble getting it out.

When disconnecting the sensor electrical connector, do not pull directly on wire going into sensor.

Testing
NOTE
Allow the O2 Sensor to cool down before conducting the test. The O2 Sensor voltage should stabilize at 5.0 volts. Raising the hood may help in reducing under hood temps quicker.
