Honda Fit fuse panel showing which locations are switched and which are constant. The only unused & keyed fuse space I could find was slot 7, marked in Green. It’s usually for the “Transmission Solonoid”, which is probably empty because ours is manual. The red circles mark circuits which are always-on, and which of the two posts is the live one. The spot with the green-? seems to switch off 10 minutes after the car does. Weird.
