let me review your wiring diagrams and I’ll read the theory of operation for that circuit and see if I can come up with any ideas. Meanwhile you can take a test light and check for power just before and after every connector in that circuit until you find what is powering up that circuit.

I’m getting weary but here is what I’ve found but have no clue what it means.
the door switches have two wires each. Yellow with a black band. And brown with a yellow band on passenger side. Plain brown on drivers.
There is continuity between both sides on the yellow/black wire.
CORRECTION
There are two kinds of brown wires are in the C2 connector and there is continuity from each sides door switch connector and that colored wire on the C2 connector.
I can't find the yellow with black band in the connector.

Disregard my previous report, I still had the ground wire connected to the battery. I ahve now re-tested with the battery ground disconnected as the instructions suggest.
On the drivers side I have a tan and a yellow/black wire. On the passenger side I have tan/yellow and a yellow/black. The C2 connector from the instrument panel has both the tan and tan/yellow wires in the connector.
Testing reveals this:
The yellow/black wire on each side have continuity between each other and each shows a path to ground.
The passenger side tan/yellow shows continuity to the same color in the C2 connector and no path to ground.
The drivers side tan shows continuity to the same color in the C2 connector and no path to ground
The C2 connector for the tan and tan/yellow does not show a path to ground.
So, I am going cross-eyed, what does this tell me so far? That the problem isn't in the dash???

As an aside, when I was five or six i had a metal pedal car that my Aunt bought for me (it was a 55 Bel Air). While my Dad was at work, I decided I needed to work on it like he did on his car. When he came home from work he found me on the side of the house, away from my Mom, with the hood piece removed, the steering wheel off, the wheels off, and the pedals off. He did not yell at me but did lecture me about taking better care of my toys. He then proceeded to re-install everything, with me handing him parts and tools. When were done, he had a handful of screws, nuts, washers that I couldn't remember where they went and he couldn't figure it out either. He told me to take it for a test drive, which was successful, so Dad said "I guess we don't really need these" and put them with his tools.
As I look at my dash torn apart, speakers, out, glove box and fuse box disconnected, radio removed, instrument panel removed, etc. and a pile of screws, I'm beginning to have that deja vu feeling all over again........

Success !!!!!
After tearing apart the dash, I have no idea how long its going to take to reassemble it. I found the short!
The wire that goes to the sound bar carries the speaker and light wires. Before the new top was installed, I also replaced the roll bar covers. When re-routing the wires, I managed to pinch the wire under the drivers side seat belt bracket that mounts to the roll bar. As soon as I started undoing the roll bar covers, I had a hunch that it might have caught there.
Now to tape it up, test everything and button this beast back up.
Many thanks to all who assisted and listened to my nonsense. I appreciate every bit of help!!!!!

Without all of the help from more knowledgeable people here, I could have never zeroed in on the problem.
I put that roll bar cover and remounted the seat belts several weeks ago, why it finally manifested itself, I'll never understand.

I've lost track of the hours chasing this issue. Today alone was over 8 hours and everything is finally all put back together.
Although I must sheepishly admit, I have two screws left over! I checked and double checked everything and cannot find where they belong. For now they are in the cup holder waiting for an "ah ha moment" to strike me.

Bottom line for any further forum members with the same issue. The computer ECM/PCM does not affect the light timing function (fade and battery save) that function is handled by the instrument cluster, the ECIM and the multifunction switch. Until I eliminated them and the door switches I had no idea where to look, especially on a task that happened several weeks ago.
Again thanks to everyone for their assistance, I was ready to give up (but I hate giving up) and their ideas kept me trying things.

Do not worry about it, you gave me great guidance today. I really appreciate it!!!!!
OP
You are a far better man than I am if you can identify the location for these two screws.......they are just like the other dozen I removed and reinserted....LOL
I’ve been following this from the beginning, on the edge of my seat pulling for you! Glad you got it figured out. Your old man would be proud. It’s posts like this that keep me glued to this damn site.
OP
Thanks. I'm glad there was entertainment value too! While you were on the edge of your seat, I need to be pealed off the ceiling......
I do think my Dad would have been proud. He worked in a mill as a machinist his whole life and liked to tease me about pushing a pencil at a desk all day (which was somewhat true until I retired). Now I spend time working on my The 4x4 Guys dot com (no spaces) and tinkering with my Jeeps (2018 JLUR and this project 2003 TJ). If my Dad was still alive, he is the first person I would have called to say "I fixed it" to which he would have replied "you caused it". LOL
OP
My thoughts exactly, so I removed the side panel from the dash where the only speaker I had to remove is located and found it all buttoned up with the needed four screws. Then I removed the lower panel, under the steering wheel only to find no holes in need of a screw................
Before I put the trim piece that runs the length of the dash (near the windshield) I inspected the instrument cluster and also was unable to find any missing screw hole.
I am 99% certain that they belong somewhere on the drivers side of the dash. I removed the center dash section and the radio from the passenger seat and lined everything up on the floor of the Jeep on that side along with everything I did in the glove box (unmounted the small fuse panel to inspect the wiring to Fuse #4.
I'm a bit OCD (its contagious, I got it from m wife) and it IS driving me a bit crazy to have these screw left over. I will go back to the Service Manual to see if I can figure it out.
