Reply to "PS 1 Locomotive conversion to TMCC Where do all the wires go."

You can wire the constant voltage module direct to track power, problem solved.  If you want directional lighting, then you need to supply more information.  I typically replace all of that for a TMCC conversion.  The smoke unit can be wired to the smoke output of the ERR board, that gives you command control of the smoke.

You can use the existing PS/1 electrocouplers with TMCC as well.
