Yep. The trick is to locate either the lighting rheostat or a light that's
connected to it. It's nice if you can find one that's convenient, but if the
only wire you can identify is halfway across the panel, hey - it's fair game.
Tie all the new stuff together and run a wire to the line you decided to splice
into.
