The overhead light on my FG-X (& BA) comes on when i open the door or push the dash button (BA), so has 2 switches. Maybe an easier way is to use the map light, controlled by the internal switch (?) When you push the lens. It has to have permanent power to it, maybe earthing to the roof bracing. You could piggyback of it. You would need a min of 1 amp only as that is what your phone charges off, but it might by 5 or 7.5 or 10 amps from the factory. The fuse will tell you, but that is also for all other lights on the same circuit as well. You can buy female USB plugs. The wire from the fuse box probably runs up inside the A Pillar.
