More info in case you get down to looking at wires and switches?
Winnbago labels small wiring like this:
If we find labels on wires or drawings, we can use this chart to "decode that info fro the from and to connection points. That will often let us know if it is a battery supply or ground, etc.

I think the correct switch for the awning operationis on this drawing, sheet five:

The details on that drawing show us the switch from front and also turned around as if from the back. That back side lists the wire ID that should match the labels on the wires.

Looking at the view from back, it gives us the wires to expect on each pin of the switch. Note FFK, FFU, FFM, etc.? Looking in the ID chart it should tell you what to expect if you get into checking power getting to and through this switch!
Getting the switch out of the mount can be one of the bigger problems with them as they use a set of mini "clamps" at the top and bottom which makes it easy to them to slide it in and let the clamps flip out to hold it in. But we may have lots of trouble compressing those clamp gizmos to get the switch out!
Maybe you don't get to that but it may help if you get there?
Best of luck!
