    So I opened up my 20" G4 iMac for some cleaning, SSD HD upgrade, and new fan replacement and I found a strange looking cable that seemed unplugged.

    Looks similar to the Airport antenna plug but what is this extra one for? Bluetooth module?

    That is for the Bluetooth antenna. It doesn't plug into anything unless you also have the Bluetooth module and the small middle antenna to connect the two. Don't forget to reapply the thermal paste before closing it.

    FYI - that unplugged cable is NOT for the BT module. Its too big, the module actually fits next to the airport card under the logicboard:

    I bought the module off ebay for $10 and plugs right in. If the imac didn't come with it that all you need to do is take a razor blade and cut the plastic covering that plug.

    So then it's still a mystery as to what that plugs into?

    This loose connector is for BT antenna. It goes to wireless antenna module located on faraday cage, under plastic shield. See attachment for details.

    You apparently didn't read my post fully.

    Judging by the looks of it, since it is round, it may be the airport cable that plugs into another airport cable extension that leads to the bottom user accessible ram/airport card slot area.
