Chime for power rear window

It just started raining and I realized I left my rear window open. I love having it open but I always forget to close it when I exit the truck. Has anyone come up with a way to add a chime for when the window is left open?

 

I think there's some app or something to help people not to forget to leave their kid in the car, maybe you could use that. Just substitute "new born child" for "open rear window"

 

I have a bad habit of leaving the back window open on occasion too, got lucky and never had it rain though.

 

Wire another switch to the rear window in parallel with the sunroof open alert switch, whether you have the sunroof or not.
Alert will pop up on the screen.
