I can’t seem to find the pinout for my Bluetooth module (BCM92046MD), as per photo:

In particular I need to know which pins are for D- and D+ Background: In an attempt to activate Handoff/Continuity, I’ve installed a BCM94331CD wifi-bluetooth combo card. Wifi works fine, but bluetooth is unrecognised by System Profiler. That suggests to me that I need to connect to D-/D+ cables to my my wifi card adapter. I soldered up a dongle to what I thought were the D-/D+ lines on the old bluetooth cable socket. But when I tried to boot, I only got a chime, a white screen, and no further. So, I may have got the pins mixed up. Any help would be greatly appreciated!

You really need the combo card Broadcom BCM94360CD. Activating the Bluetooth on it. Take the current BT card out. This is what I used iMac 2009, iMac 2010 and iMac 2011 – Apple Broadcom BCM94360CD – 802.11 a/b/g/n/ac with Bluetooth 4.0 kit
