I drilled holes in the side bulkheads below the mic and phone jacks for the LEMO plugs. The LEMO plugs will be used by LightSpeed or Bose headsets that will use ship's power, rather than battery power. I don't have this type of headset now, but I decided that I will probably get at least one in the future, so it is easier to install these plugs now. The required holes are oval, so I drilled a 1/2" hole with a Unibit and then used a round file to extend the top and bottom of the holes. I cleaned up the edges of the holes and inserted the plugs.
