Ive been having rough starts and loss of power over bumps and pin pointed the source of the problem. Its a faulty wire towards the back of the engine. It has extremely little play and when it cuts out you can hear a relay clicking. So now I know what it is I was wondering if you all could help me find how to replace it and what systems it is involved with. See attached for exact location.

Wire color and wider angle picture (or where it heads to) might help get you some responses. Is this a 4.0 or 2.5? Can you nail down where the clicking relay is?

Just off the top of my head, I'm wondering if it's the fuel pump harness.

looks like the wiring harness going to the CPS.
If it's the CPS harness, it should have an orange wire, a brown with yellow wire, and a tan with yellow wire in it, and the only relay that's really associated with it, is the automatic shut down relay in the power distribution center.

The wires are orange brown and yellow. That is it.

I throw the CPS sensor code intermittently. Makes sense now. How would I fix the male connection going into the female. Just cut back on the wires?

If it's really tight, I think I would cut it and add some additional wire. (or find out what's making it that tight). A little solder, heat shrink, and tape. If it's the connectors themselves, you can purchase aftermarket connectors in most auto parts stores.

Well my thought is that since the Jeep is old the wires are broken internally or something thus it responding negatively to movement. I was going to cut the wires and reattach the connector.

Update: Ends up it was the pigtail on the harness side. Took it to a shop to have them put a new pigtail on. Guy calls me today and said it was working good up till he double checked it on down the line towards the transmission and said that it shut off again. Wanted more to replace the CPS sensor. Im gonna do it myself and save some $.
