No strap on main awning. How do I know the length I need?

That's a good question. There is a light switch just outside the bathroom door, which is between the kitchen and bath. Could be for the kitchen. I'll see if I can get it to turn on with the switch, but nothing seemed to turn on when I played with that.

I'll try the light-squeeze method on the other lights. :) So glad I found this forum. Thank you for your responses. I'm about as green as they come. Enthusiastic, but green.
