I have installed lots of sound systems but I am not an expert in electronics so when I opened the tender on the K-27 I was a little lost and need some advice.  I will be using the Phoenix sound board  and all I need to know where do I pick up track power?,  where do I get the chuff signal (do I use a reed switch?), do I use a reed switch for the whistle signal (I am almost sure that is what I have to do)?
