This was for a new install so I do not have any wires or screws for this drive
New install meaning new mobo too?
EDIT: To be clear, the dvd uses the same cable as a regular harddrive
The mobo should come with an IDE cable (as well as a bag of screws, just find the ones with the proper threads. Otherwise hardware store sell metal screws which will fit), just plug the drive into that. If you already have a second drive filling up the cable, just buy another cable. Local shops as well as Best Buy etc carry them.
AGFAIK, a dvd can be used on a newer 80 wire/40 pin cable, or the older 40 wire/ 40 pin IDE cable.
You'll also need to hook up the power for it- it's the same 4 pin connector used for case fans etc. Your PSU (power supply) likely has a about 4 of these. If all are used, then daisy chain.
Hope that helps.
