Default O2 sensor, which side?????

I have a 2004 Grand Limited, 4.7 (of course) and I have a code that reads "bank 2 , sensor 1, heater circuit low." Now, I know this is a problem with an O2 sensor, upstream from the converter, but which side is bank 2 on if you are staring up at the converter? Thanks guys, I appreciate it!

bank 2 is the bank that cylinder #2 is on. the cylinder numbers are on a tag attached to each injector pigtail. Or bank 1 is the one with the most forward cylinder head. Im pretty sure bank two is the passenger side off the top of my head.
