Recently I converted 3 MTH UP Passenger Cars (20-3229-1) to LED lighting. I wired them directly to track power (with a 330 ohm resistor) and I don't like that and want to change it. One time I was running the cars and one of them derailed and I could smell burning electronics. I want to use GRJs board. Since I already have the lights in the car, would I just solder the wires from the lights and the track power to the board and that's it? Or is there more to it? @gunrunnerjohn Also, I was looking on Hennings trains and there out of stock.
