I just got my two 4-4-0s back from having dcc decoders installed. I had printed this topic so the guy could see the diagrams, etc.
When I picked them up, he said the one from Micro-trains set was not like the one from Model Power that I had purchased sometime ago.
He got both decoders added, but Micro-trains version was more delicate work. What he told me was that the wiring shown in this post did not match that in the locomotive from the Micro-trains set.
