Ron,
Momentary contact accessories like the 30-11028 MTH water tower and the ATLAS Century uncoupler tracks baffle my wiring abilities. Is it correct to assume that they can be some-how wired to the AIU Switch posts?
Just wire the as you would to their own controller pushbutton. Substitute the "1" and"IN" terminals of an AIU ACC port for the terminals on the pushbuttons.
One last imposition: How do I wire to MTH DCS the operating freight or passenger platforms to maintain/control constant lighting while independently activating the “disappearing freight” and “boarding passenger” features.
This one's a bit trickier. I have mine connected to the AIU, however, it was several years ago and I can't lay my hands on the wiring plan that I used.
One thing that I can say for sure is that, if you wire it to the AIU, you cannot also have it wired to its manual controller. The operating freight and passenger platforms use a latching relay that will cause a conflict between the AIU and the manual controller.
