Bank 2 is the right side of the engine. Sensor 2 is post catalytic converter. Follow the pipe from the right side of the engine. Sometimes they cross or make an X, but make sure you get the one for the right bank.

Edit, they do cross on a 97 with a 5.7. If you follow the exhaust from the right exhaust manifold, there will be a converter, the oxygen sensor will be behind that converter.
