As PPGT94 said, it should be just a standard IDE ribbon cable. Check for a picture or details from where you ordered it from. Most also use a floppy power connector for drive power. If the drive won't be within 18" to 24" from the motherboard then think about a IDE/USB adapter.
The black connector shown will plug into the back of the drive. It has the power and data pins all in one. on the bottom side is the standard 40 pin header connector for a standard IDE cable and a separate floppy drive power connector which powers the drive through the adapter.
