there should be a usb port on your ps2 located in the front somewhere and you just plug the keyboard into it.

Nah, (Sorry if i can’t explain this very well, but ill try and make it simple) The software in your ps2 doesn’t work well (?) with your keyboard. Like eyetoy and computers. Hope this helps!

Also, why not try it instead of asking lol?

Edit: Oh sorry, did you mean where to plug it in? Well if it’s the phat ps2, look near the eject button for a blue panel.The panel has two slots in it.Put your keyboard’s USB thing in one of them. If it’s the sk1nny ps2 then there’s one one slot under the eject button and one just to the right of it. Good luck!
