2022 F350 diesel passthrough or upfitter stub?
 

I'm still trying to make sense of the wiring in the 22 F350 diesel. I need to get two wires from the cab to the upfitters. I struggle with the grommets. What are these? Passthrough wires or are they the upfitter stubs? Sorry for the dumb questions but I just can't get my head around how these things are wired. This is a grouping of three or four blunt cut wires taped together.

May help. If not, there's other videos available.

You are my new hero, brother. I've been looking for weeks. I did not come across this video and didn't look high enough behind the glovebox. Not sure I have to remove the battery but the bundle in the video looked exactly like my image above. I will tone them out later for continuity to make sure and that's that. Thank you so much.

There's another video where they removed the fender liner instead. Seems the pass through wires are a bit more difficult to access.
