Need specific instructions to bypass the NSS

It is not a plug in relay, you can follow the wires down to the starter, it should be near the battery.

OK, found that. It is a small connector, I suppose it could be a relay, that goes down to the starter. It has 2 small wires going toward the starter. A red and a green with black stripe.

Where do I find the NSS relay ? There are 5 relays in the fuse and relay box. None of them are marked NSS.

Sorry, my mistake on labeling. It's not the NSS relay, but the start relay. The NSS provides the ground path for the solenoid of that relay. On stick shifts, this is directly grounded, and on automatics, it's grounded through the NSS. So if you can figure out which line is the ground for the solenoid of the relay you ground that and it should start.
 
In the diagram I emailed you it has a picture of the NSS connector and it says what the grounding path is (what terminal gets grounded on that connector) so you can figure out what wire you need to ground and still have the reverse lights. You splice into that wire and provide a solid body ground.

Anyway, whats the big fuss about the "numerous safety concerns" of defeating the NSS, if you have a manual tranny like I do than you can engage the starter in all gears and at any time so it wouldn't be any different that that you just have to be careful not to start in gear.
 
OK, here's how it's done.....

Ran into the dealer mechanic at a wedding reception Sat. night and was telling him what I was trying to do. The last time i had it in the shop he experienced the finicky NSS and had to jockey the gearshift for a couple minutes to get it started. So the mechanic said just stop by the shop and I'll show you how to bypass the NSS and start it. It's so easy! In the relay/fuse box under the hood, there is a starter relay with 5 pins. 3 smaller and 2 bigger pins. After pulling the relay out of the socket, insert the 2 ends of a small jumper wire into the 2 larger slots of the relay socket. That puts juice to the starter, even if the key switch is off. Of course the key must be in the on position for the engine to start. Gentlemen, this is what I was looking for! Thanks for the replies and thanks to bajacalal for the wiring diagram. I have it printed out and will keep it for future use.
 
If you start a stick shift in gear, without the clutch (with the transfer in high), chances are it's gonna buck and die. Do the same thing with an automatic and the torque converter is gonna let it slip enough to drive right off. The 4.0 has a couple of seconds at start up, when the engine revs well over a thousand.
IMO an accident looking for a place to happen. Many 4X's with a transfer, have a clutch switch, so you can't start it without the clutch being in.
A little off topic, but if your oil filter "O" rings are leaking and the oil gets on your starter, t will eventually seep inside and mess with the contact at the brushes. Starting turns into a random thing.
If your NSS bypass, doesn't work out for you, try cleaning the starter brushes, with a good spray solvent.

To answer your question, if your Jeep does drive over somebody and the insurance adjuster, can find a defeated safety item, you pay and they don't.
 
I had this same type of problem and after searching the forum found the info on the NSS. Mine would start intermittently and then not. Tore my NSS apart cleaned it, jumped in and it cranked right up. Second time out it wouldn't start. Make a long story short. wired in a pushbutton starter switch for the times it wouldn't start by the key. Felt it is the start relay but I did this a few months back and haven't had any further problems. NSS is still in the circuit so vehicle won't start in gear and have back up lights.
