I realize this is kinda old but I just did this on Saturday 3 hours after buying my Fusion. There is a 7.5A fuze that is marked spare. Its a 12VS terminal. For the application I am using it for, this is what I wanted (kids DVD players) I used the jumper plug like suggested, put a 10A in one and a 7.5 in the other. I ran into a problem installing the cover to the fuze panel so I drilled a 1 1/4" hole in the top where it would have just the jumper exposed. Iran the wire over the pedals and behind the center console side panel by just removing 2 screws and moving the seat back and forth to gain better access. Then I removed the back panel on the center console using a screwdriver, figured out where the plugs would hit the sync computer thats behind there, and then drilled 2 7/8" holes with a hole saw. Installed the plug, wired the ground to the back screw on the center console side and popped the back panel back in.
