I have done several decoder installs in diesels without any difficulties. Now I want to do a Brass Steam install. I'll use a NCE 408. Not sure wear to locate the decoder. Not much space in the boiler. I get the orange and gray to the motor, But exactly how do the Red and Black connection go please. That drawbar with it's whisker wire has me confused. Appreciate someone who experienced with this who can give me a detail explanation.
Thank You
Bob
