O2 sensor in 2.4

Hello I have browsed thsi site before and always found it fascinating!! I have a 2.4 2000 alero...Have a few mods and is a work in progress vehicle..I will definately post a pic soon! My trouble lately is with putting in the air fuel gauge I just bought. I do not know exactly where the O2 sensor is located in the 2.4 engine.. I thought it was the connector to the right of the engine cover that says "2.4 twin cam" the purple wire but when I tap into it the meter just reads "rich" and it doesn't dance around just stays in "Rich"/.. Please help if anyone knows where the O2 sensor is!
Thanks
