The O2 sensors are located in the exhaust piping.
One (bank 1) is on the engine side of the Catalytic convertor.
Second (bank 2) is on the other side (exhaust end).
There are manufacturers that make universal fits that will go in either location. Be sure to specify the rear sensor when you go to the parts store.
It will look like this....
It threads right into the exhaust pipe.

if u have one oxygen sensor then u need to take a deep look at the bottom of ur car it will be somewhere at the Exhaust pipe if u have a catalytic converter then u will have two oxygen sensors one before the catalytic converter & the other will be after the catalytic converter. Note: the catalytic converter is located at after a little bit of beginning in Exhaust pipe.

Oxygen sensors are always numbered like this:
Bank 1 sensor 1
Bank 2 sensor 1
Bank 1 sensor 2
Bank 2 sensor 2
some manufacturers use a kind of shorthand that reads different, but means the same thing:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2
Bank 1 is always the side of the engine where cylinder number 1 is located and, of coarse, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only 1 bank and it is always referred to as Bank 1.
Sensor 1 is always the upstream sensor (The one located BEFORE the catalytic converter)
Sensor 2 is always the downstream sensor (the one that is located AFTER the catalytic converter.
Most GM engines have #1 cylinder located on the left bank, (or Driver's Side) of the engine,
So, the answer to your question would be that you are looking for the sensor located before the catalytic converter on the right (or Passenger Side) of the truck.

B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter
You didn't say which engine you have, so I've included the diagrams of both 4 cyl and 6 cyl so you can see the banks

SOURCE: diagram were bank 1 oxygen
Bank 1 is the side with the #1 cylinder, In your car it is the bank that is nearest the firewall. Sensor 1 will be the one BEFORE the catalytic convertor, or nearest the engine in the exhaust manifold or pipe.
