You are not able to hack off the end of a composite cable and just wire in an s-video end. To make an s-video cable for the PS2 first get the pin out of the Playstation, you can get this from <a href="http://www.gamesx.com" target="_blank">www.gamesx.com</a> , then get a 4 pin mini din at any local electronics store, like radio shack, and while your there get 2 rca plugs, some wire, solder, and solder iron if you don't have one. You will also need, the heart of your cable, an AV adaptor. I would buy a cheap one on this because all you need is the end that plugs into the Playstation, it should come fully loaded with all of the pins. Cut off the wire at the base of the box with the composite out and r and l audio there you will see 12 individual wires. What you need to do now is open up the end that plugs in to the Playstation and see what color wire goes where. For S-video you need luminance, chrominance, and gound for luminance and chrominance. Find what color wire goes to those pins and run those wires to your s-video male connector and then run the r and l audio wires to your RCA plugs, the cable of the AV adaptor is short this is where the wire comes in just solder it to the wires that comes off of the AV adaptor. Snap back together the end that goes in the Playstaion and wrape up any wires that are exposed and your done. All you have to do now is try it. You can find the pin out to S-Video on the web.
