Aristo Bridge Rectifier Board

Greetings,
I posted this on the Aristo forum too. Any help is apprciated.
I discovered I was having what seemed to be polarity problems with my Revolution receivers, so I got the CRE57079 to resolve the issue. I am running track power. The boards came with no documentation on installation. Can anyone guide me on to where to install them on the locomotive?

Thanks,
Rick
