Could someone tell me how to get the schematic of the iMac 27" mid 2010 logic board and / or bluetooth card? The service manual that is in this site does not include this information.
What I am exactly looking for is the meaning of the five signals that join both elements. More specifically, I am looking for the signals USB D + and USB D- to replace the original bluetooth 2.0 card with a Wi-Fi 802.11ac + bluetooh 4.0 combo card installed in the mini PCIe connector, and I need to bring these two signals to the new card. Right now only the new wifi works, but I would also like bluetooth 4.0 to work.
Thank you very much.
