Three 21 to 8 pin adapters, making it easy for you to fit an NEM652 8 pin NMRA plug fitted decoder into a locomotive which has a 21MTC connector installed.
Unlike other adapters, DCCconcepts 21 pin adapters are already pre-wired with function 3 / Aux 1 / green wire connections and also have easy to solder to connection points for function 4, 5 and 6 should they be needed.
