does anyone know what ind of “harness” the ho athearn sw1500 uses?
The newer RTR ones have both a 9 pin and an 8 pin connector, you can use either. Plain 9 pin decoders with no harnesses are usually cheapest.

I just put a Digitrax DZ125 in an Athearn SW1500. I do not use the Athearn wiring harnes. I hard wire all of my decoders. I have also placed a DH123 in an Athearn SW1500.
alright , thanks for your help
