I went to the local motorcycle shop today, and ended up buying the last BikeMaster "power outlet socket" (part number 15-1668, 12V, 15A). It cost $8.00, as opposed to the ridiculous $84.99 that Kawasaki wants for their Versys plug (EIGHT DOLLARS) retail, and fit perfectly. The only significant difference (and really not significant at all), is that the BikeMaster unit lacks the square "key" to limit rotation once installed, but that square key really is unnecessary. It has a tight fitting, soft & pliable rubber cap, and even has the bullet plugs needed to just plug it into the harness. Furthermore, I used a 12v relay that I pulled out of the fuse box of an old, junk Honda as opposed to the required Kawasaki relay. Bottom line is this: if like me you are squeamish about spending the hundred or so dollars for the factory accessory plug (parts only, mind you), consider the lonely eight dollar BikeMaster power outlet socket which is likely collecting some dust at your local bike shop. That, and an easily sourced relay from a Japanese car in the junk yard, and you're in business. I'll snap some pictures of the components next time I have it apart.
