I know this is an old thread, but I just wanted to say thanks to BCParker for providing those pics. I never thought to take a picture while I still had the factory wires in there. Looking at it now, I realize my second set of wires was all jumbled up. It was time for me to install my third set and I figured I'd try to make it pretty this time.
I bought a set of NGK V-Power plugs, a new Performance Distributors (Davis Unified Ignition) cap and rotor set, and an XJ specific Taylor Spiro-Pro 8mm plug wire set which is supposed to be the same thing as the Mopar Performance wires. I started out using the "longest wire goes to the furthest away plug" method that many folks on here recommend. I quickly became frustrated as I knew my wire set was made specifically for my XJ but I just couldn't get it to look right.
I finally found the above pics and they were a lifesaver. I thought I'd add a few more with some of the hoses and cables pulled out of the way to provide a little more clarity for anyone else trying to recreate the factory wire routing. Looking from the passenger side fender:

I was worried I was going to have to get some aftermarket separators for the 8mm wires, but as you can see, they will fit in the factory wire guides. I don't think you could go much bigger though. I also don't think you could route the wiring as neatly with the aftermarket separators.
Another helpful hint for anyone using an OEM wire set or an XJ specific aftermarket set... Trying to sort out which wire is which can be confusing because despite the fact that the longest wires go to the furthest away plugs, the shortest wires
do not go to the closest plugs! Arrange your plug wires in order from longest to shortest. They will be in order as follows:
#1 is the longest
#6 is the second longest
#3 & #4 are the same length and fall right in the middle
#5 is the second shortest
#2 is the shortest
Hope someone finds this helpful. :wave:
