How to replace bluetooth 2.1 by 4.0 on iMac 27 mid 2011

I have a relevant question ?

Someone can explain clearly how to do this replacement. There is part of the answer but not complete, so I will explainb what I know and I hope somebody could help me to complete.

1/ explanation of ifixit to deassemble imac : perfect

2/ we need bluetooth antena cable extension : easy to find

3/ we need BCM94331CD no BCM94360CD (because it don't work with windows if you use vmware)

4/ we need an adapter Mini PCI-E Adapter for BCM94360CD/BCM94331CD V3

And here began mi doubt : the adapter V3 (possible to encounter in ebay) have normaly D+ / D- conector.

What I don't know is if this adapter need also VCC (3.3v) and where connect to the adpater if needed.

after, I don't know the type of conector D+/D- on the adapter, to do a cable from the adapter to the original cable of bluetooth of the imac (mid 2011).

I don't know also the type of conector of this original cable and if it have to be male of female.

So has you see , I keep with a lot of questions and I need clear explanation to avoid to have bluetooth not working after doing this upgrade.

Thanks for your help

Right now the best source of info on converting systems for Handoff is this site: Continuity Activation Tool.

Right now I wouldn't recommend trying to convert a two board iMac system as the needed parts are not easy to find and you do need to make some non-reveraeable changes.
