GGG,
I have access to the tech manual. I know there are a few wiring diagrams in it. I never took the class at MTH as I came along too late. I have learned as I go on these but have been doing HO scale DCC installations for over 20 years. If I understand correctly, I can use a PS3/2 stacker and the PS2 slave to control both sets of motors in the turbine and fabricate a harness between the two.
