There should be up behind the passenger kick panel. But I'm having the same trouble with my 450. Can't find the damn things. I had no problem finding them on my 2019. I watched a YouTube video of a Ford Tech who had trouble finding them also, he ended up removing the BCM in order to locate the inside wires. They were tucked way up behind the BCM for some reason.

If you have that kick panel completely removed, you should be able to spot them using a flash light. They could be completely wrapped in black tape.
There are a couple threads with pictures but the pictures aren't of the best quality. Here is one. https://www.ford-trucks.com/forums/1...tions-fyi.html

The pass through wires on my 22 F250 were right under the PCM on the firewall and behind the passenger side kick panel.

looking for help hooking up the pass thru wires behind the passenger kick panel. I have a 2017 F350. The wire are so short I would have strangled whoever is responsible if I had the opportunity. No matter how I contort my body I can’t get two hands down there to get a butt connector, wire nut or anything else to get a good connection. There’s just no room to do anything. Anyone have any recommendations on tools they’ve used, techniques, etc ? Thanks!

I’ll take another look at it today but I don’t think it’s really the problem. The passenger seat doesn’t back off enough to allow me to get my arms at the proper angle to reach in & hold the wires while installing a connector (Super Cab). I tried attaching a butt connector to the new wire then holding it with the crisper in one hand & trying to get it over the pass thru wire & then crimp it but so far it being a bad angle I can’t get a good enough crimp. Maybe a legit crimp tool & new butt connectors instead of a combo tool & old connectors. Wish I could get the passenger seat out. Maybe take a look.

I've given this some thought on how to get a connector on the wires for the 17-19 trucks (supposedly the wires are longer on the 20+ trucks) and I thought that an inline WAGO connector would work well, as you could reach up there with one hand and connect the WAGO. It's still not easy to get up there, but trying to get both hands up there is not easy.
