I just replaced a faulty sensor on my 2004 GMC, and although not all trucks are the same, here is the correct answer for my application and probably most similar vehicles (Tahoe, Sierra, Yukon, Escalade, etc) with the same drive train 4.3/4.8/5.3l. This should apply for any vehicle 99-06 on the full size truck platforms.
The system is setup almost like you would expect:
Bank 1 Sensor 1 - Driver's side, before catalytic converter
Bank 1 Sensor 2 - Driver's side, after catalytic converter
Bank 2 Sensor 1 - Passenger side, before catalytic converter
Bank 2 Sensor 2 - Passenger side, after catalytic converter
I searched around forums to find this answer, but no one was for sure and couldn't find it in their Chilton's or similar manuals. I disconnected each one, used my engine code reader to see which error was thrown after disconnecting them successively, and through process of elimination came up with the above information.
