I want to install a KeepAlive in a Richmond "sound Value"4-4-0, where can I find how to do that. Specifically where on the decoder do I solder the Keep Alive leads?Thanks.

The Richmond's were not Sound Value.  They had an earlier and better Soundtraxx decoder made for Bachmann.

Soundtraxx has various instructions on their website.  You can probably get assistance from them.
