You don't need any internal wires to make a sound card work. You just plug it in, connect the external speaker wires, load the drivers and you are in business.
With Windows 9x you might use a CD analog cable. This would be 4-pin female at both ends. It would connect between the sound card and the CDROM/DVDROM/CDRW drive.
With Windows XP you don't need the analog cable as XP is capable of digital playback.
