This appears to go from your video card to either VGA out or with the included adapter, plug in to the black part to become composite out. The two black parts plug together.

Standard molex Y splitter.

S-video or VGA out?

I can bring them to the next monthly, or I`ll just mail them out. No worries on the mailing cost as it`ll be a buck or so in a padded envelope (ive got a few here)
