Aux switch for rear lights

[MyOutdoors]

Thank you in advance, ive been doing a search and found some great info/video on the aux switches. I have a 2024 tradesman with the snowchief package, aux switches, 5th wheel prep, 6.7 cummins. I'm adding a roof mount led beacon, ditch lights and rear receiver/bumper flood lights for plowing.

The ditch lights & beacon light are no problem hooking up to the factory plugs under the hood. What's confusing me is how I hook up the rear bumper floods to one of the auxiliary switches. I know there's 2 wires out back underneath by the spare tire. What do I need to do with the supplied wire connector/harness that plugs under the dash by the e-brake to make those work?

Addressed in this sticky:

You'll need to cut/splice that jumper or repin it to carry one of the pass thru wires from the AUX to the cab to the rear.

This is a roll-up thread that should answer most if not all questions regarding power availability in the cab.

A lot of the credit for technical detail goes to @Jimmy07 without whose help and guidance much of this info would be hard to assemble.
There are other contributors, you know who you are. If you recognize a photo as one of yours, shoot me a PM and I'll add the credit.

Leads to this thread (post #6) on how to connect using pass-thru wiring. The 21+ trucks have 4 extra pass thru circuits that the 19-20 trucks don't have.

Let me start by saying I am truly sorry for once again bringing this up.
After I plug this harness in to the gray connector under dash the single wire is my pass thru #6?
And than that loose wire can be hooked up directly to a device with in side the cab ?
What do you all do with the extra looped wires that are designed for the rear of truck ? Stuff them up under dash?
Thanks again.
