Why do you want to remove the BCM? The wire you need is in a connector on its face, so there is normally no reason to remove it. That said, there is no inherent danger in removing it, assuming you don't damage it in the process.
The wire you need, A10 in connector X3, was the same in 2008, so should also be the same in 2009. Yes, it is grey.
