I used the board that for the non plug-n-play (first one I did) and had wires everywhere. I run battery power and one of the boards went bad and the loco quit. After a year or so looking for the board a friend said he would just rip out everythng and start over. A lot of trains I work on for Rosenberg Railroad Museum are not plug-n-play and this friend told me about a blue board from Robbie at RLD. The museum does not use smoke on the locos and using the blue board is pretty straight forward. Power in and power out, forward lights, back lights and always on lights. Just a thought. Good luck.
