Mario,
I know this topic is well over two years old, but if you can help me explain the wiring arrangements to operate and control the original RailSounds 2/2.5 board (as well as the ElectroCoupler and back up light) with the new Cruise Commander, I'd really appreciate it.
I'm doing the same with the Chesapeake & Ohio Yellowbelly Hudson that came out a year before this locomotive, and they likely have the same wiring requirements.
