I finally figured out that those 2 pins on the inside of the tailgate are contact points that meet up with 2 others in the cargo area of the Jeep. Once I realized that, everything made more sense to me.
I tested the 2 contact pins in the cargo area and didn't get a light, so I figured that the problem was either right there, or SOMEWHERE behind those contacts. First I tried cleaning all 4 of them, and nothing. Then I got to looking at the 2 good ones a bit more closely trying to see how everything was hooked up. I found you can only pull the pin about a 1/4" forward before the connection behind it starts to grab and stops it. So I tried that on the ones inside the Cargo area, and SURE ENOUGH, one of them pulled completely out.
That was the whole problem, one of the contacts wasn't connected.
So I got underneath, and was shocked at what I saw.
The wonderful shop that that installed my KC Back-Up Lights had done a really bang up job.
All the wires were hanging loose all over the place.
Loom was stripped halfway off and hanging.
Cut wires weren't removed, you name it.
And in their Mickey Mouse process, apparently they disconnected one of those wires, God only knows why. Of course, they never hooked it up again.
And these guys are supposed to be professionals?
Of course, I fixed it all and tied everything up when I was done.
I'd love to name them outright, but don't want any kind of BS ramification attempts.
So I'll just say this. They're supposed to be the best Jeep Offroad Shop in Phoenix, Tucson, and Albuquerque. Anyone in the area should know EXACTLY what company I'm referring to.
It doesn't mean that everyone that is associated with them does this kind of work, but it does say that they must not have very good Quality Control.
And this is not the first issue that I've had with this place either.
Needless to say, I was pretty steamed.
They won't EVER get my business or recommendation for anything again.
In fact, quite the opposite.
I'm no mechanic or electrician by ANY means.
But I'm learning as I go.
And I'm finding out very quickly, that if you want something done right, well...you know.
I've had better luck coming here, talking with you all, and learning how to do things myself, than the BAD LUCK that I'm having with these "so called pros".
Thank you all, and thank God for this forum.
Maybe now I can get on with my mod.
I'll post it if it works.
Some of you are probably wondering why I'm writing a book about this.
The answer is simply that maybe it will help someone else.
