I'm having a problem with installing DCC in an Athearn RTR AC4400 that is "DCC Ready". I have an ESU LokSound Select decoder with an 8-pin NMRA plug, but when I plug it in to the circuit board already in the locomotive, it just sits there and buzzes like there isn't a decoder at all. Are there any steps I'm missing or a wire I need to connect/disconnect in order to equip this loco with DCC?
Thanks.

Some locos have two DCC connectors,an eight and a nine pin with jumpes.You have to remove the jumper from the one that's no used.
Thank you! It works great now.
