Those are not the main upfitter wires, they are located under that relay box. They are tapped up pretty well. You can us a flat head to release the relay box from the mounts and get better access. Look for the bitter end coming off that relay box harness. They are all labeled and look to be 8-10 gauge.
The wires that are switch controlled are probably 12 gauge, the 4 wires that Ford put in place to go back inside the cab are more like 18 gauge or smaller. There are no 14 gauge or lower that goes back inside for wiring up items.
I've got a brand new 2023 Tremor with the dual batteries. Your video is the only one that helped me...THANK YOU! By the way, I'd love to see your radio install, I need to find a clean location for mine.
Those are the same wires that I have on my F450 as they match what is under the hood and at the kick panel and they are way to small for what I need. I was not able to get the wire through the grommet on the passenger side as there is so much in the way. Had no problem getting it through on the drivers side though. Excellent idea, thanks for the idea
Sorry dude, but you did this the really hard way. The big wad of up-fitter wires are under the relay box...it's looks like a very well taped up "short tail". Unravel all that tape and you have all the wires with a label that tells you what colors go to what. Two of the up fitter switches can take 40 amps, the other 4 switches all run 25 amps. The two 10 gauge wires are the 40s, the others are thinner diameter wires. I'm running an air compressor with one of my 40s and a DC/DC charger (for my camper) with the other. Ford should have given at least 4 more inches of wire length to work with...but it is functional once you pull off all that tape.
The wires are under the upfitter fuse box, take your battery out or take the wheel well liner out, I ended up taking out the wheel well liner, then u don't really need to release the clips on the fuse box, there's a tag on the wires that say which wire is for which switch, just did it today

Great video... saved me a lot of headaches
Thanks for sharing.
Nice looking truck 👍🏼

I was gonna say, there are 6 switches, so there has to be 6 wires. If he's only finding 4, those can't be it.

I am having trouble accessing the wires, I released two tabs but not enough “give” to access them. Do I need to remove the battery and tray to access?
Pull the fuse box, the harness is under the upfitter box buddy.
Wrong cables they are under the small fuse box
This video is wrong. They are under the unfitter relay box on a 23-24.
Wrong wires. These are not connected to the aux switches. Please don’t use this as a guide.
Yet another u tuber that doesn’t know what he’s talking about.
Tremors don't come in the platinum model. I have a 2023 F- 150 Tremor.
Super duty….
