2 separate wires here. The first picture wire is broke. And the rest show two ends of wire with it disconnected at center and no ground to hood

Not sure of the question. That is a ground and should be repaired and I believe attaches to the stud on the hood In the third picture.

Sorry about that. The first thing I want to tackle is the ground wires. Im not sure where they all attach. The broken one comes up to the hood? Ill bring up the codes I'm getting after I fix the ground wires.

Starting with the battery ground clean both ends of the cable and battery post.

On the inside of the fenders where you have pictures of the grounds take them off and clean.

Inside the Jeep on the footwell sides there are those studs also, left and right sides.

More then likely if your getting the o2 codes they are probably bad, replace the o2's with OEM.

Ok I checked them with a multimeter and they were all sending a signal at operating temp, but maybe the heater wires aren't working correctly ill check resistance on all them too.

Sorry I'm not very electrically inclined. When it comes to electrical schematics I'm pretty lost.

I ordered the ground straps to replace mine from the company in this video. Great replacements.

Here is a video outlining the locations. He also goes into detail on the length required and the eyelet sizes so you can order them.

Just went through this with my new to me 2011JK. O2 sensor was throwing a code so dealer I bought it from replaced it with a new Bosch unit. Still got code so the sent me to a jeep dealer and they discovered that the Bosch unit was not comparable, replaced it with factory unit and problem solved.

Thanks all. I found a few leaks looks like from the manifold gaskets, and where it meet the piping for the cat I also tested my cats with infared thermometer and the cats at the rear had similar temperatures on both ends the front ones had higher temps up front does this mean my rear cats have failed as well? Could the exhaust leak throw something off?
