Xbox 360 ground vs common ground

Hey all…

since I have no idea how to wire a pcb I have a question, does this pic show a common ground Xbox 360 controller:

If not, where can I find a diagram for a common ground one?

Is there a model number I should be looking for to have a common ground wireless pad?
