Lionel offers few if any wiring diagrams. For this engine a Mini Commander is marginal at best. It was made for motors smaller than the one in this engine.
It has no input for a chuff switch but a Railsounds card does. Not sure your Railsounds will work here though. Lionel tends to omit TMCC functionality in converntional engines even though the boards look identical to TMCC capable versions. Also I suspect your smoke unit puts out continuous smoke, not syncronized with the chuff sounds. If true you will need an interface between the chuff switch and the smoke unit, either GRJ's super chuffer or as I do, a double pole reed relay which takes the switch signal and sends that to both the smoke fan motor and chuff in on the Railsounds board. You can't simply use the switch wired to both inputs.
