Hey guys just bought a new cat and muffler for my exhaust system. I wanted to unplug the o2 sensor to replace it but can't find the ending. The wire goes into the body and can't find the end to the plug its a 80 just for reference.

 

Nevermind found out its a temp sensor in the cat. Does a 80 come with a o2 sensor ? I just bought one for the car but being told it doesn't have one and can't find the location
