Hello! My check engine light recently came on and I was told my o2 sensor located at the end of the catalytic converter( not the one by the engine) is not working. I ordered the part, but the problem is I cant seem to locate it. I looked all around underneath and all along the exaust system. Still no luck. I do not have the part yet and I dont even know what it looks like, just that it is a plug with wires coming out. Could someone please send me a diagram or please tell me in exact detail where this o2 sensor is located? Thankyou for your help and replies!

i´ll send you a PM with apic.

It's right behind the stock skid plate in the center of the underside of the Jeep. It comes right out of the side of the exhaust. You can't miss it if you follow the exhaust pipe from the engine all the way to the rear.

yeah its hiding, on top of the tranny
