install wifi and bluetooth 4.0

Hi Rafael, look for this card on amazon or ebay --> Broadcom Bcm94360cd (40-50,-EUR) and this adapter --> DN Mini PCI-E 52pin Adapter für BCM94360CD / BCM94331CD Ohne drahtlose Antenne.

You should first remove the original bluetooth card 2.0 and the wifi card. Then your done.

Grab your new Wifi and Bluetooth card. All of the antennas that you disconnected from your previous cards will need to be attached to this card. It can be difficult to attach the antennas properly; be patient and do not use excessive force. The Bluetooth antenna wire (marked with the "BT" tag) should be connected to the port marked "J3" on the card. The other three antennas may be attached to any of the three remaining ports. Once all the antennas have been attached slide the Wifi and Bluetooth card into the port. Push the card flat against your Mac Pro's Logic Board and use one screw to secure the card in place. Installation complete! You may now reattach your other devices and the Mac Pro's power supply.

• Some of the cards have the ports on the back side of the card. You should still connect the Bluetooth antenna wire to port "J3".

If you also use your Mac Pro to boot into Windows be sure to download the Boot Camp 5.1 drivers from Apple. Once you have completed the download install the Broadcom drivers included in the package while booted into Windows.
