How can I get that wheel to work on my computer?

We might need some more information. For example:

Have you plugged it in?

If so, what happens when you do?

A quick google search shows its for Xbox, PS2, and GC, with no mention of PC compatibility.

Well I had it plugged into a PSX to usb adapter. but the pedals and brakes show as a button.

[bump]

Do i need to install the Drivers?

does it have any drivers?

Closest thing you'll get to drivers is the PS2 -> USB adapter driver, which you've probably already installed.

If the pedals are mapped to the semi-analog buttons or triggers (which is fairly common in el cheapo pedal sets), then having them mapped as a button is the best your going to get I'm afraid.

just go buy a cheapo wheel thats aactually for the pc

Well I'll geuss I stick with el controller
