I have searched online for the location of the O2 sensor and found this page http://autorepair.about.com/li...c.htm. I see the connection to the exhaust pipe and I disconnected it from the one going up into the engine. The wires lead into a bundle of other connections and I can't see where the actual sensor connects into the manifold. I have an EX but the connection into the exhaust pipe looks just like the one shown for the DX and LX models. I bought a sensor and the wire harness looks exactly like the harness of the wires going into the engine. Anyone have advice?

 

The picture on that website is wrong; Dx,. Lx and EX are reversed
