Hey guys, I have a 2001 XJ with the 4.0 and I did a 4wd swap on my XJ. I keep ripping out the wires on my rear downstream O2 sensor no matter how high and out of the way I route the wires from the front driveshaft every time I take it 4wheeling. I have been researching for the longest time to see who makes or where to actually get a working simulator so that I can just get rid of the downstream O2 sensors altogether and not worry about that CEL cause I'm a bit OCD when it comes to the CEL. I don't care about all the exhaust BS that I read in other threads cause that doesn't answer the question. I am not messing with the pre cat O2s at all either. I know that nothing mechanically will go wrong with my jeep as I drive around with the wires ripped out of the O2 plug in the rear downstream. So basically only thing I want to hear from you guys is who or where do I get a set of simulators for the downstream O2s on a 2001 XJ with the 4.0. Thanks for any helpful responses!

 

I dont run simulators so I cant help with that. You can extend the wires and move them to a more remote location.
