I have a 95 owner's manual handy here, and as far as I recall it's the same for the later type (I don't think I have the 99 manual any more). I will be extra conservative and not post the picture, but I probably could if I had to.
The little clamp should face back, and be held down by a thumbscrew.
Place the jack handle down first, folded up with the hinge toward the right (passenger side), and the crank portion toward the left and back. Now put the jack on top of it, with its base to the right, and the cranking socket to the rear, slightly to the right of the thumbscrew. The clamp should now close over it.
