Perfect for Athearn (and others) this new 9 pin (female) 21MTC (Male) adapter board allows the popular 6 output ESU 21MTC LokSound and LokPilot decoders to be easily added to your favorite locomotive. More and more locomotives now have front and rear headlights and front and rear flashing ditch lights. In order to accommodate for this in DCC 6 function outputs need to be used. As 8 and 9 pin DCC plugs only allow for 3 and 4 outputs respectively, this new adaptor board will allow easy conversion to our 6 function decoders. 4 Outputs though the 9 pin plug and 2 more on solder pads. As Athearn normally uses 1.5 volt bulbs it is often easier to use the supplied resistance in the Motherboards for those lights. This new adapter board DOES NOT include 1.5 volt light resistance for the additional 4 outputs (AUX3 - AUX6) that do not already go through the 9 pin JST plug. ESU decoders also include the ability to dim the outputs to match perfectly the onboard resistance with the adaptor resistance if needed.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Excellent (\u003ca href=\"#\" title=\"C-7: Trainz does not provide grading for parts.
