You do not need four wires -- black and red should suffice.
Can you recommend the type of connector that needs to connect to the riser board? I purchase a s15 pin Slim Line SATA power to 4 pin Molex power cable. The Molex only had black and red wires. The 15 pin connector forced me to do a lot of triming to make it fit. In the end, my drive got power, so I believe I need four wire Molex and a differnt slim line 15 pin connector.
