I own a Bachman Baldwin 2-6-6-2 engine.  I want to install an Airwire decoder and Phoenix sound.  The engine has a plug and play socket on the control board.  To install an Airwire decoder would the C-19/K27 drop-in decoder work or will Bachmann's supplied decoder plug or the Airwire adapta plug be needed.  And is there enough room for a Phoenix sound module as well?
