Hi, I have a 1992 F150 with a 1996 6 cylender engine in it. The fuel milage is awful, and I was told that the O2 sensor has gone bad. I checked adnd there are two O2 sensors, and the wires coming out of the O2 sensor has been cut. I'm guessing the wires were spliced somewhere. What I'm wondering is where is the connector where the wires go? I'm greateful for any help.
