How to change rear heated o2 sensor?

I have a 95 maxima, i just read my trouble code and found it to be the rear heated oxygen sensor, i'm gonna replace it how hard is it and can you point me to some instructions?

thanks

go under the car. its a 22m bolt head. there should be a plastic covering under the car, pop that off and the rear o2sensor cables should be there, and just unclip and replace with a new one.
