FIRING ORDERS NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired.

Autozone.com has some great wiring diagrams. I looked and your Jeep seems to be there. Go to Vehicle Repair Guide>chassis electrical>wiring diagram. You may need to register, but I think it's worth it. I'm looking at the diagram for your vehicle so if you have any trouble finding it just post a comment and I will try to assist you.
The wire should go into the same harness as do the remainder of the wires from the switch. If you tell me which pin the wire attaches to in the harness plug I can tell you what it does/ The two center ones opposite the clip are for the starter.(Plug facing you, clip at the top, two center pins in lower row) Likely the wire you are looking at is to the starter relay But, if the reverse lights are on, make sure the neutral switch is adjusted properly before doing anything else...if it is, a contact inside the switch may be broken and bridging the reverse contacts.
when you take alternator out of play. the vehicle runs. i would be replacing the alt. these units are complex containing modules, regulators that can give you erratic problems, but i think u answered your own question alternator
I have the Haynes repair manual 1987-2003 Jeep Wrangler with all of the schematics. Which wiring scematics do you need and maybe I can scan/email the pages, if this legal? Or can maybe answer questions you may have, keeping in mind I am NOT a mechanic but I can read plans/schematics
If you want to rewire the vehicle, assuming that you will not be changing any systems, you can usually find complete new wiring harnesses from both the dealer and from aftermarket selllers like Quadratec and JC Witney. Buying the complete wiring harnesses will be alot cheaper and less time consuming than trying to make them yourself. These wire assemblies are just a plug and play deal, you disconnect a harness and replace it with the new one. They may even include some instructions. If you need further assistance with custom wiring or diagnosis, I would recommend getting the service manual for the vehicle from the dealer or used ones from eBay ($30- $100). The factory service manuals have complete wiring diagrams and schematics as well as full diagnostic information. These service manuals are NOT like the ones found at your local parts store (Chilton or Haynes). The factory service manuals are like complete blueprints for a car.
