I just did the mod on my K2's in an effort to remove RFI from the audio. It is much easier to just remove the left side panel. That gets you enough access to the mic connector and the ground loop without the trouble of pulling the whole front panel apart. I did not wrap the wire all the way around the connector, just soldering it seemed secure enough.
