1995 BMW 540i: Where exactly is o2 sensor located

Resolved Question:

Where exactly is O2 sensor located on 1995 BMW 540i? I was told that there was more than one. I know Chevys but not BMWs. I want to change it myself. My diagnostic tool told me that it was bad. I was told that it was on the engine....OK, great....but where and how to get to it?
