Hooking up a steering wheel to the arduino

Sorry im not that well versed in reverse engineering and im not really good at taking things apart but i want to hook up my old steering wheel to the arduino uno and then program it so the wheel controls my ps3. The code i can handle, the thing is i dont really know the pin out of it. It should be pretty simple because it has a lan conector or how its called, sorry. I was wondering are there any tutorials on this or maybe some of you could tell me how to reverse engineer this? Thanks in advance.

Part number or photo could be handy.

KenF: Part number or photo could be handy.

As would the manufacturer's name, but preferably, all three.
