DCC/RCC Connector Pin & Wiring Diagrams and Instructions

Beginning in 2001, new locomotive models started arriving with a plug and play PC board.  The board is designed to allow easy installation of either a DCC (Digital Command Control) decoder or RCC (Radio Command Control) receiver.  On the board is a standardized 12 pin female plug that DCC Decoders Receivers equipped with a standardized 12 pin male plug.  

Provided here are diagrams that show pin and wire location for installing DCC or RCC systems in your locomotives.  This information is useful in situations where the locomotive or DCC decoder or RCC receiver does not have the 12 pin plug.  The information is also useful for performing  modifications or alterations to the electronics of locomotives.  Consult manuals and instructions provided by DCC or RCC manufactures for specific information regarding their products.
