If you want to run something inside the cab the pass through wires are your best bet just pick an upfitter wire on the driver's side then attach a wire to that one and to the pass through then to the equipment you want to run on the inside of the cab.
not really any need to run extra wires through the fire wall.
No relay is needed when using the upfitter switches they already have relays.

 

Thanks for the clarification.

 

Finally done. Worst part was the short pass-through wires on the passenger side access panel. I quit searching for an ACC hot wire and just wired it to Upfitter Switch #1. I appreciate the tips from archer3 for the top on removing the fuse box above the UpFitter Switch wires. Helped a ton!

 

Here is a picture of the final install and a video clip of it in action.

Thanks for the help guys!

 

Not a problem gascan. I've gotten a lot of help from other forum members and whenever possible I like to pass on what I've learned so others can enjoy their 2017s as I'm enjoying mine.
Like others here I'm still learning so a little knowledge from those who've figured out things or acquired knowledge of how things work helps immensely and saves a lot of headaches too.

Thanks to all of you members who pass their knowledge.
