I have been having issues with the Switch bank which controls the Tow Haul, Exhaust brake, park Sensor which is all located below the Uconnect. Sometimes it works, other times nothing, or 30 min down the road it works. The dealer a couple months ago replaced the switch bank and everything worked. Now it works as I mentioned and the diagnosis is a short in the wiring harness. Problem now is that the harness has been discontinued. I really don't understand that when the truck is only 8 years old but what do I know. And with what did they replace it with if anything. Can someone direct me to help find this part or recommend something else?

Do you have the part number for the harness?

I don't. The Truck is at the dealer in Spokane so not to far but I would think they would reach out to Dave Smith.

Sorry, I'm of no help, but, man, what a terrible turn of events.
Having been on (too many) forums for these trucks, cannot say I've heard of that issue until now. Best of luck getting it repaired!

But, are you saying that whole switch bank was intermittent or not operable at all prior to the first replacement of the switch bank and then it worked 100% of the time for a couple months and is now intermittent again?
If so, that seems to me to be either the new switch bank or possibly a bad connection. If the new switch fixed the same condition previously.

Those switch panels are quite inexpensive both new and used (<$100) and plug and play I believe. I'd be thinking about replacing that again personally before going down the wiring harness rabbit hole.
Just a thought.
Plus if you had a dealer do the prior replacement, is it under warranty?
And how did they diagnose the wiring harness, just by default since the switches are new?

Shame you do not have part number. You could check with Spaldings
I doubt whether your dealer will check with Dave Smith!

You're out of warranty, get it to a good diesel shop and to heck with the dealer service department.

I'd also ask your question on Cumminsforum or one of the others.
Huge knowledge base and you have a seemingly needle in the haystack type issue.
Good luck!

How about a wiring harness from a truck in a junk yard?
