I need to know where oxygen sensor bank2 sensor2 is on 2001 ford windstar 3.8L engine?

I know that bank2 sensor2 is on one of the catalyst converter there's 4 sensors total and the catalyst converters r not side by side one of them is coming from the front of motor/van and the other is coming from back of motor and i don't know which is bank2.

As you sit in the driver's seat, Bank 2 is the right hand side & sensor 2 is the second sensor in that exhaust pipe, starting at the engine.

The bank 2 is the exhaust pipe coming from the front of engine sensor 2 is in the catalyst converter.
