Several brands of substitute wiring harnesses are available from the various DCC dealers, in varying lengths and configurations. I get mine from Litchfield Station in Glendale, Arizona, but Tony's Train Exchange and others also have them.
It looks like they do: JST 9 Pin Harness 3.25" to 8 pin NMRA plug (long wire) and JST 9 Pin Harness 1.25" to 8 pin NMRA plug (short wire).
These items at: Empire Northern Models.

Hello, I have DH123AT decoder which I want to install in loco equiped with NMRA 8-pin socket. Does Digitrax have some wire harness that could substitute harness provided for Athearn locos?
Thanks.
