So I have a horrible habit, I leave my sunroof open. I love my sunroof and open it at any opportunity and often leave it open when parking the car. This can lead to issues when water starts to fall from the sky. Mad dashes across campus or into the parking lot at work to close the roof as my seats get wet come to mind.

So I'm considering a electronic solution, I'd like to put a switch in the area ahead of the roof that would close when water contacts it and activate the switch that closes the roof. (To stop the roof once its closed I'll put a microswitch that will be pushed when the roof is closed)

In reality its a pretty simple idea except the roof only operates with the key on. My question is. What is the simplest way to get power to the sunroof all the time. Can I simply run a wire from the positive terminal of the battery to the sunroof fuse? Does the key break the power before or after the fuse?
