I've heard that this is likely made by a company called AMP. However, I need to find a part number and a source where I can order more of this connector. Male and female end both pictured; I need to buy 6 of the male end and 2 of the female end.
For what it's worth, these are used in Sega Crazy Taxi cabs, and I believe are the same style of pin as what is used in Astro City cabs and probably several other Sega cabs.
