I took apart a cigar socket USB adapter & found the guts fit here perfectly. So I soldered some wires on, but I haven't found the switch I want yet. Eventually, I'll be able to turn the USB power off, on, or set it to be controlled by the key. For now, I'll just solder its power wire to the key-switched feed.

I'm doing some other mods at the same time, which is why there are more wires.
