I bought and installed the Fenvi t919 wifi card on the PCIe slot (Mac Pro 5,1). There's a bluetooth cable (picture below). One end goes on the wifi PCIe card, and the other end apparently goes on some 9-pin connector on the motherboard, which I can't find. I've already checked other threads where it takes you through this process of replacing the old bluetooth, soldering, etc. I just want to know if there's a 9-pin connecetor for that cable on the motherboard, and where. I would imagine if they make the cable that way, it's because it connects to something lol. Thanks for any help.
