Color Code Your Wire - John Waitkus

A simple solution to "what wire goes where" is to color code your wire.   Make sure that you use only one color for each type of connection.   Some examples; Red for Block Power, Black for Common.   White for Switch Machine Common, Blue and Yellow for Switch Machine Power.

Also, make sure you use a large enough wire size for the application.  18 gauge wire will work fine for layouts up to 4' by 8'.   If your layout is any bigger, get a larger wire for your connections.   This will assure that you don't get a voltage drop to the remote sections of your layout.
