Can someone tell me where to locate this sensor on a 92 5.2L ???

I have a chiltons and have looked in there but can't find it where its supposed to be. Its supposed to be near the generator but all I see there is the coolant temp sensor and coolant dash gauge sensor.

 

Nevermind, Im an idiot. I confused the Air sensor for the coolant sensor. The coolant sensor is behind the generator, the air sensor is on the side of the engine (passenger) near the fuel rail. coolant dash gauge being one wire to left (when your standing in front of truck) of the coolant temp sensor (2 wire).
