Well, these photos, although clear in my computer, do not look so clear here. Let me know.
1st photo is the switcher with the original board. I know all the hook ups here which at least is a good starting point. The original board is clearly marked, "motor", "lamps" and such. I can see where the ground wires.
The remainder of the photos is the Train America board. The only hook up clearly marked on this one is for the motor. I am new to TMCC so no expertise although I did just complete and ERR upgrade to an older Williams Brass Daylight with little trouble. But I would be guessing on hook ups here.
Let me know on the photos. I do have a camera with a macro lens and could take closer photos if needed.
