What number fuse is it for cigarette lighter on 2001 mondeo?

The fuse is F68 situated at the far left of the fuse board behind the glove box. You will find 3 slots to this fuse, you will still use a mini fuse (15amp) however, if you place the fuse in the top and central slots the cigarette socket will only work when the engine is running..... in the central and bottom slots, the socket is constantly live.
