2018 321RSTS Roof Solar Prep Wires go Where?

[bmanz]

I have GoPower solar MC4 outlets on the roof however I am not able to figure out where they terminate. I found the 8AWG cables that go to my battery disconnect that are for solar. Those wires go into the front cap of the RV and are copper. A continuity check confirmed they are not connected to the roof.
The wires on the roof are tinned copper with many more strands. I pulled the sticker off the wall inside and drilled a hole for my endoscope and there are no wires inside the wall.

Any help on this would be greatly appreciated. Thanks in advance.

They are probably somewhere in that vicinity. I used a tone generator to verify mine where behind the wall sticker before drilling. Mine came from the roof and looped back up to the roof somewhere before going back to the battery area.

Not surprising that Jayco has no records or drawings of these featured wires.

The reason they are tinned is because the box on the roof has different wires already attached. The wires coming from your battery disconnect panel are wire nutted to the box just below the roof surface.
I literally just removed my roof box to check because my positive lead is open somewhere. I’m trying to hook up my solar panel.

Found wires & setup is complete

The wires were in the same wall where the sticker was placed however they were in the adjacent stud cavity, not exactly where the sticker was. The roof connections suck, I removed the existing setup and installed new MC4 connectors.

Can you tell me what wall the wires were in. I never had a sticker on mine and my positive is open from the roof to the battery area. I have a 2017 321rsts. I removed the control panel area and the corner wall behind the toilet that hides all the wires and still can’t find a red 8 gauge

Location for my wires

Wires were inside hallway wall but closer to bathroom side and not control panel side. Please see pictures where blue tape and post it note are located. (Sorry my picture is rotated). I cut an access box and installed a blank cover when I was finished. See where the cover plate is located in relation to the bathroom slide covering.

I used a tone generator to find my rooftop wires. They were in the labeled wall, however they were in the adjacent stud wall cavity as well. I think I will need to install new MC4 connectors on the roof. One is already pretty corroded.

Found my wires. Why would they cut the positive wires?
Why not let the customer do that. Not everybody wants a charge controller mounted on the wall.
I removed the vertical piece of trim on the left side of the wall and separated the panel and there they were. The red wire was cut and wire nutted.
Thanks again for your help
