Solar panel pre-wire

[MaceMan]

My 2018 ACE has what looks to be a MC4 connection for solar power on the roof. It's supposedly pre-wired so my question is where do the wires in this connection go? I don't have a solar controller on this model yet as far as I can tell.

My first thought is a charge controller hidden in a cubby somewhere. My ACE is a year prior so I don’t have it pre-wired.
I would bet a quick call to Thor might reveal the answer.

Those wires obviously come down through an interior wall.
Try to figure out which wall it is, and then start the search inside.
Happy hunting!
