The MX644D is one of the latest generation of ZIMO sound decoders and has the 21 Pin interface built in. There are no speaker wires on this decoder these connections are made to the loco's own circuit board where speaker connections will be found.
TOP view of socket
This side fits uppermost in the vast majority of UK installations, check very carefully before fitting as they can be fitted upside down and this will damage them.
