You don't even have to disconnect the battery, these are just Fords normal air bag warnings. just take the bolt covers off, remove the 2 8mm bolts, pull the air bag out and disconnect the wires. Then remove the steering wheel bolt and then screw it in a couple of threads by hand, start hitting the top and bottom of the steering wheel with your hands to try to rock the wheel in and out until it comes loose and goes up against the bolt that you left in to prevent the wheel from flying up and hitting you in the mouth or damaging the wiring. then undo the bolt and voila!! steering wheel is off.
