Does anyone have access to the wiring diagram for Lionel American Flyer U33C 6-48187? (or similar) Also, other than the smoke unit's 16ohm resistor, are there any differences between the smoke unit that originally came with this loco (S gauge) and a Lionel O gauge fan-driven smoke unit? Obviously dimensions are different. Wiring connections/plugs I'm not concerned with. I'm pretty confident I can use a different Lionel fan driven smoke unit and just swap out the resistor to a 16ohm resistor. But if anyone knows otherwise, please let me know.
Thanks in advance,
