[Elecraft] Heil mic adapter question

[H.Cary III]

For Christmas, I will be getting a Heil Dual side Traveler head set and
boom mic to use with K2.
Heil doesn't list Elecraft on its website (strange considering all the
good press from Elecraft for Heil!) to determine which adapter connector
to use.  I'm thinking it is likely the Kenwood 8-pin but that's just a
guess since Kenwood hand mics work so well with this radio.
Do any of you use a Heil mic/headset with a K2 and which adapter do you
use?  Any help will be greatly appreciated.
Merry Christmas/Happy Holidays & 73,
