Instructions
Plug your multitap into the PS2 controller slot of the adapter. The PS2 controller slot on the adapter will be a female port, considerably larger than the USB connector (pictured).
Plug the USB connector into a USB port on your PS3. The USB ports are located on the front of your PS3, below the disc slot and power button. Old models of PS3 have four USB ports, while newer models have two.
Turn on your PS3. The PS3 should automatically detect the multitap, and any controllers plugged into the multitap. Insert your favorite game and start playing.
