It will be located on the side of the exhause system (before the exhause). Basically, it just unbolts and the new one screws in. NOTE: Make sure to get some anti seize and put it on the threads of the new sensor. If you don't, you will have a really hard time removeing it if you need to replace it again in the future.
Let me know if you have other questions.
