The o2 sensor is on your exhaust manifold, the only thing that plugs into it besides your egr.

Whats that black tube looking thing right below it? Are you sure the O2 sensor wire isnt hiding somewhere inside there?

I think the wire for the o2 sensor is routed through the back of the engine (behind valve cover). It runs with the plugs for the 2 switches behind the valve cover.

I think the plug on the last pic is the one on the section that leads to the coil..... if it is then no connection is needed there.
