Aux Switch Wiring

[haleme]

I am adding Aux Switches to my 2018 2500. It did not come with the Upfitters prep, Snow Chief or any options I can see to support Aux switches.

That said, I have purchased the correct switch panel to replace my existing panel and the kit from AirDelete.com to complete the job.

My question on the wiring is on what I found from the factory when I started to do the install.

The factory wiring already has the 5 wires built in for Aux switches.


The colors perfectly match the Upfitters Schematic for my truck, so I reason these are the wires that would be used to go to the Aux relay box if it was built from the factory.



So, the question is, where do these 5 wires terminate?

Did a little more digging and found I have the blunt cut wires under the PDC.

I seem to have the same plug with the 5 wires for the aux switches on my 2016 3500 that doesn't come with the aux switches from factory. replaced with the appropriate switch panel for my truck, and the aux switches actually lit up; Aux1/2 on battery and Aux3/4/5 with key on "run".

you mentioned above the blunt cut wires. Are those leading to the aux switches?

For the aux switches to light up, the 5 wires must be grounding some where.
Not really wanting to cut or splice into the wiring harness at the plug, unless I have to.
Hoping to find the ends of those 5 Aux switch wires.

How did you end up getting yours hooked up?
