There are a number of harnesses. There are also generally THREE (3) "BUS" circuits that are tied to various modules. One harness is ahead of the firewall (eng compartment) and other harness(s) behind firewall. it is designed so that certain electrical systems are on specific BUS circuits. I have heard of many with stalling problems and also of wipers or headlights turning on and off on their own.
A technician told me that some of the circuits "fail safe" meaning that when they malfunction, headlights may go on or wipers may runs etc.
My particular problem with my harness was for many times (5) diagnosed as a bad module here or there (refer to my earliest posts in these threads). Some modules were replaced more than once or twice. In my experience, some of the modules were actually OK, but the harness was shorting out modules and ignition switch, etc. I would not be two miles down the road from what was supposed to be a successful repair only to see same "crazy dashboard light show" happen again and again. They did not believe me until i filmed it on my phone's video capability.
Quite frankly, with the new harness my Jeep is running so smooth and true and is like it was always meant to be. It idles smoother than when I bought it, as well as consistently performing well in all kinds of Wx.
The repairs for all the modules replaced totaled $2100 for mine, which I paid over a series of repairs. (Oouch !!!) Then I got in touch with Jeep Customer Support and they were, IMHO, great about dealing with my issue. I was totally documented with dates, times , receipts, etc. I even had them speak directly with Jeep Service Manager as well. In the end they covered to cost of the harness so... I don't know what the actual expense was but BOTTOM LINE.. it was worth all the agro that i went through.
Years ago I personally installed a new wiring harness on my '72 Honda 350CL motorcycle and it to never ran better.
So, as one can see, I am "all about the harness" as being a prime source of many of the symptoms I read in this forum. Sadly, only one way for you to find out...
Best o' Luck
103,000 and running smooth

I have a 2001 jeep grand cherokee. I am currently having problems getting it started. It will start for 3-5 seconds and stall out. I checked the fuel rail and Im getting plenty amounts of gas. However on rare occasion it starts up, my gauges and sometimes windows and door locks dont work. Although my dash lights do. I checked for a faulty instrument cluster and a bad ground... not the problem. Oh and the security light is on! Any insight please? Thanks

This actually happened to me before and after a few days of diagnostics, my mechanic discovered it was the Skreem Module causing the problem, which I had replaced. If you google Skreem Module you'll see it controls a lot of the sensors and starter, etc.
If it's not that, a friend of mine had the same issue (start for 3-5 seconds then stall out) and it was just his key, which he had to get replaced.
Hope that helps!

I have a 2005 and just had a similar problem fixed. The key wasn't being recognized by the computer. Do the locks respond when you use the key to unlock/lock the doors? Mine didn't and after looking through the manual I found the engine will shut down after 2 seconds if the key isn't recognized.
The part is about $170 and most of the time the dealer has to reprogram the key if it has a build in chip. Good luck, Joe D

Ok, before I put my car in the shop this week and get ripped off. I want to state again my problem to see if anyone has the same and what were u told. When my car doesn't start, I turn the key put it into drive the back into park and it starts right away. While driving, my dash lights goes nuts, and all the lights for PRND light up all the same time and then the car won't shift gears. My head light flicker off and on night, and my raido she to go from station to station without me touching it. Either its haunted or falling apart. Any advice.
