it takes like 20 minutes to pull and clean the nss dude
That plug is in the engine bay just to the passenger's side at the rear of the valve cover. Unplug it, jump the Jeep side of the plug, and test start. If it works come up with something more permanent.

I'd get a voltage reading at the starter to be sure. With the key in the ON position, you should have approx. full battery voltage there. I'm assuming you don't, but the meter never lies.
If you don't, you have a control electronics problem of some sort. If you've jumpered the NSS, the primary suspects can be the starter relay, a bad starter cable, or a bad ground. All three are suspect here.

no there should not be that much B+ wire exposed. if bypassing the NSS does not work but will work with jumping the starter I would go after the click you hear under the dash. a relay that clicks does not mean that it is making good contact. check with a VOM meter or test light to see if the starter relay is tranfering power through the relay.
