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. Its 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.
