I'm thinking about replacing my O2 sensor to troubleshoot a rich/poor gas mileage issue. I know where the actual sensor is (bung on the exhaust) but don't know where the O2 connector plug is "in the back of engine" according to Clark's?

Seems like an easy swap out but where's the dang plug?

It is attached to the same bracket on the rear of the intake that houses the speed and reference sensor connections. O2 is the round plug.

it's on the firewall right smack in dead center of engine bay.

mine was a big orange plug. i think that's the stock plug. it's like the size of a carrot nub hehe

once you pull the o2 sensor out of the exhaust you can pull on the wire, either down or up, and youll see exactly which wire/connector it is in the back there near the firewall. its in the zip-tied bunch back there at the top.
