It was kept in the "secret" compartment next to the nav's table by the lower bunk...and was also super handy for warming your hands on a cold winter day or tracking down the expeditor that forgot about you on midshift!!!
The -00GE has part numbers for the adapters...run them through FedLog and see where that takes you! I'll tell you though the ones i have in my CTK look like they have been locally manufactured. Pretty rough lookin but they get the job done.
