How can I turn on the ditch lights on my model? The ditch lights are always off but will turn on when the horn is activated. I'm using and NCE power cab. This is a KATO model with a Digitrax SDH104K1A+FN04K1 Combo. Seems like I need to rewire it or something.

To turn on the ditch lights on a KATO model using a Digitrax SDH104K1A + FN04K1 combo, connect the ditch lights to available function outputs on the FN04K1 decoder (such as F1 or F2). Then, use your DCC controller to activate the assigned function (e.g., F1 or F2) to turn the ditch lights on. Make sure the function is mapped correctly and the decoder is properly installed.
