bachmann ho gp40 dcc decoder

[restorer]

looking for a  dcc decoder (NOT SOUND) for Bachmann emd gp40 .  It's a Ho (miss. kan.tx.) #63519. The web site shows it has a factory installed 8 pin plug.   I'v checked Digitract with no luck so far.  Thanks

Bachmann makes their own decoder you can install:  http://shop.bachmanntrains.com/index.php?main_page=product_info&cPath=264_274&products_id=1827

Since the 8-pin plug is an industry standard, all you need to do is make sure there's room for the decoder and wires inside the locomotive for the decoder of your choice.
