Which Buttons are which on the G27 wheel and console for PS3

[jwilljtr]

I am completely new to the G27 steering wheel and still a little vague with the PS3. After searching for days, I am still unable to find a simple guide to tell me what button is what. For example which button on the G27 is the PS3 X or triangle or L1, R2, etc. I guess I will then do button assignments, etc.
