Hi, I bought a MacPro two weeks ago and have just taken delivery of the bluetooth module and Airport Extreme card design specifically for the mac pro. I've put the bluetooth card in and connected up the cable that has "BT" label on it. I thought it would be same for Airport Card but there's 3 cables to choose from labelled intuitively "1" "2" and "3". All with the same connectors on the end and all taped up together. The Airport Extreme card requires 2xcables to be connected. Anybody out there have a MacPro with Airport pre-installed and can take the side off and have a look at their config for me please? They are supposed to be a service center install hence don't come with a manual, they refer you to the AppleCare Service Source Website.
