Are you looking for the matching side of the green connector?
If so you might be able to just get by with any SIL connector that has the same pitch, just measure the distance between pins and find one that matches... Be aware doing this you won't have the polarization ripples so you need to pay attention to how you plug it in... As for locating the real plug, it's just a lot of leg work going over manufactures sites looking for a match, or browsing some online suppliers that have good pictures...
