Fuse #2 doesn't do much. It's the horn and the lighter (if you have one). You could run your wire through the firewall grommet and tap in to the green wire at the horn relay if you wanted.

EDIT -- or, if you don't have a lighter, use the white wire coming off the 53|28 under the dash. That's what feeds the lighter and it should be right there for you, if you can find it.
