Yes, I thought your voltage divider was backwards.
I used a second Power supply instead of a voltage divider because I was a little worried about the variation on the 12v line. With your voltage divider you get 2.1v at 12v and 2.6v at 14.5 - does that work? Is that enough for the Pi to see it as high/low?
