Thanks @Cameo, that's what I was thinking the solution was. I'll be checking mine this weekend. I haven't had any issues yet regarding this. Thanks for posting your findings!

I found that disconnecting the affected wire harnesd and running it back behind the larger orange wire harness then back over and re-connecting achieves the goal of moving it away from the metal AC line it is shorting on. Did not have to zip-tie.

Better to address the issue before it becomes a problem. Trust me its no fun when the motor just randomly shuts down going down the road

I tried to disconnect it and I couldn't get it done. It was hard to see on the backside how to un-clip it. I said screw it and zip tied it. It looked like the other wiring harness in the conduit should be clipped to the A/C line. Mine was not clipped to it so I clipped it back on to the A/C line.

Thanks for the tip. Checked my truck and sure enough it was in the process of rubbing through. Zip tied it and all is good for now.

As it happens I found another wire harness rubbing on the upper control arm on the drivers side just the other day and had zip tied it up out of harms way so the rest of you may want to check for this one as well.

Ditto, mine was starting to rub thru. Maybe if the hard black plastic stuff was used instead of the fabric type this wouldn't have been an issue. Zip tied away. I'll have to check the drivers side upper control arm next

I found mine was rubbed through the silver heat tape and the plastic loom in one spot near the egr cooler. Removed the heat tape and loom to inspect wires , all was well. So re taped it up and will keep an eye on things.

Can someone get a wider shot of where this is? I can't seem to find the wires based on the photos posted. Thanks

Here is a higher view. To the left of the orange conduit you see a aluminum fitting for the A/C compressor that has a bar code on it. In my picture you see small black conduit that goes up and over that A/C line. Right behind where the A/C line goes down to the A/C compressor is where you will find the rubbing on the A/C line.
