Cigarette lighter is the 15A fuse second from the bottom on the right hand column.
http://www.nicoclub.com/FSM/maxima/1994/el.pdfYou can find a full diagram on page 9. It's kind of a pain to read and not as compact as the original label on the fusebox cover, but it's still got the same info.
Also, page 103 has a specific wiring diagram for the cigarette lighter, including a cleaner view of the fuse box and fuses that affect the lighter.
Welcome to NICO, by the way.
