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.
