This is my return loop located under Big Ten Curves. Can someone please tell me how to wire this? Feel free to download the picture and draw your solution on it.

A simple solution is a DPDT switch. You reverse the polarity of the whole loop. You power the loop by this switch.
With DCC you can buy a automatic device.

I found a reverse loop module called MX7 from ZIMO. The MX7 is a single module, the MX7/3 is a triple module.

Maybe someone (Art Luescher, are you reading this?) can tell me how to wire it in this particular example, together with a MX31ZL.
Thanks my friend. I found a german version of this manual, but I could not find the english.
They just did an article in the July MRR that shows how to wire a wye a couple different ways. I know its not exactly as you planned, but they are wired somewhat similar.
