somehow the wires to my o2 sensor broke off so i have to get a new one now, whats the sensor in the CAT considered ? i called autozone and they said they only have the one befor the cat and after the cat and i ask them which is the one in it and they dont have any idea what im talking about , is it easier to just go buy one or grab one off a crashed car in the junkyard? the sensors seem to be pretty expensive.

There are only 2 (post 96 cars) one in the header and one in the rear of the cat. Just tell them you need the post cat one, it sould be the same one.

 

You have the primary o2 and the secondary o2. If it's the one in the cat it's called the secondary o2 sensor.
