Hey IT,
Those are gameport connectors from the stick to throttle (pictured.) If you are running xp you will not be able to use them as they are DOS driven. Same problem we old CH Gameport users run into
I have an old stick that looks remarkably like that one. It is an old Suncom Raptor. It was gameport as well. I used to love that stick prior to my CH. Hehe, felt "good in the palm."
