I have some questions on wiring a 4-8-4 bachmann, Im thinking of putting the pc board from a spectrum in the tender and wiring the loco that way. it seems most n steam decoders are in the tenders I.m also curious about some good guides for doing this pretty inexperienced but have electrical knowledge any input is appreciated. I alos have some model power engines that need lights wired considering a backup as well, all in time. Hve wondered about putting PC boards from Spectrum engines in for lights ect.
