Thanks Railman63. That helps some. This loco came NIB from an estate. #25963 ON30 280 Little River. There is a plug-in decoder #44915. Also in the box was a new decoder with no name on it, pickish purple heat shrink and 11 wires. Also loose is a black capacitor indicating 25 volts. If I knew how to add a pic with this post I could show you these items. I have a suspicion now that the Bachmann decoder is not for sound and the previous owner purchased a generic sound decoder, a keep alive capacitor and an aftermarket speaker then passed before getting to it.

Looks like I can't post a pic without having it stored somewhere with a url. Any suggestions? Thanks.

Hello Folks.
I have the noted loco in my shop, and I am trying to install the included decoder in the tender for a friend. I have a nice exploded diagram of the tender showing the simplistic outline of the pcb board plus the Bachmann decoder. There appears to be no decoder instructions per se showing where to install the keep alive or the speaker wires on the board.

I did locate two wires off the pc board that appear to be for a press-on fit to the rear tender light. I'd like to confirm that as well.

Am I missing one more sheet regarding the actual decoder? Can you assist me? Thanks.
