Dvd burner install cable problem

I am replacing an original dvd burner on my Compaq Presario with a LG GH22NS30 22X internal DVD burner. The LG burner came with wires, but they are different than the existing wide cables. I’ve searched the web and know about the wide cable, slave, master but the back of the LG burner is different. There’s no slave/master switch. Only 3/4inch cable connection and 3/8inch cable connection. That’s it. The rest is surrounded by plastic.

Your old drive is IDE interface, the new one is SATA. Do you have SATA connectors on your motherboard?
