Anyone know what this is on a Cyclone 4200?

It is NOT a manual override for the awning. The awning override is on the end cap (door side). Remove a small plastic cover and insert same tool that's used to manually operate the electric slide motors. I keep forgetting to see if my RW has this plastic cover piece, but I think it does. I'm definitely curious of what exactly it's for.

So far, my vote goes for the motorized rear screen that none of us have....most logical quess so far IMO....

Here is a photo of the hole and wire that goes to the screen.
