AUX Switch Wires and Pass Through Wires

On my 2018, they're in exactly the spot behind the kick panel shown in the photo above... They have to be there somewhere.

They should be as pictured above or slightly higher closer to the glove box.

Is your Ham radio a fixed unit or handheld? I currently have my CB wired to my 15 amp, but installing lighting tomorrow that needs that plus the ten amps. Would I be fine moving my cb radio (cobra 75) to the smallest 5 amp?

Cobra wst75 requires about 3A - you'll be fine.

Found the wires! In case anyone else feels this pain on a 2018 my wires were taped to a part of the loom above the white plastic at the top of the box. The black ends of the wires were facing towards the rear making them difficult to see. I spotted a single black tip, and that led me to the bundle.

You've got that backwards. The live aux switch wires are on the passenger's side of the bulkhead and the pass through wires are on the driver's side of the bulkhead.

He has it labeled backwards.

Confirming that

What a huge PIA trying to find those stupid little wires!!! I saw one of the wire covers and pulled on it, thank the Lord that was the one I needed!!

Yours look to be about an entire foot longer than mine.

Scratch that - I *needed* the wires and I was about to run another whole set through the firewall, but then i just reached up in there and grabbed the bundle and pulled - and there was obviously another fold way up there (it's paper tape) and voila - I have 6 wires ready to use. I'm going bundle the two larger wires into one because I'll be pushing the current draw on a single wire with the amateur radio I'm installing. Common sense tells me that I'll connect the two together on the inside, but pigtail them both separately in the bay, each to its own 7.5A fuse connected to the battery - that way if either of them breaks or is cut, the other doesn't inadvertently try drawing too much current.

Can anyone confirm on the 2018's if I need to disconnect any of the plugs at the firewall to find my upfitter wires? From what I can tell, theres a black M/F plug that I could undo and also the 2 big BUS type connectors with white handles that could be undone in order to find these wires.

Any help would be appreciated!

I disconnected the big plug at the top of the fuse box just to move it out of the way for my big-wide flipper-hands to get all up and in there. They're up there, just tucked out of the way and probably folded back and taped in a position you can't easily see them. FYI, when i finally found mine, they'd not come down far enough - turns out there was ANOTHER fold up there. I just gave it a little pull (all 6 wires in the bundle) and it broke loose - at least the line tucked them up with paper tape and not vinyl. When you've got them loose, they should extend below the bottom of the fuse panel.
