2 bar map sensor ??

Okay I have searched a bit and I am not sure what 2 bar sensor I need. I have a 2005 GTO with the LS2, and need to which 2 bar map sensor will plug and play. The number I have found are:
GM part # 16009886

GM P/N: 12580698

Is either one correct?

thanks in advance,
Tony

The other may be a superceede part number but I just ordered the one above and it still exists.
