Some time ago, I asked for help wiring in a digital whistle board I purchased from Brasseur Trains that had 5 wires on it. Previously, I'd received what I thought were the same digital boards but those had 4 wires and I knew exactly how to install them. They make great whistles for slantback tenders.
Everyone who responded indicated that a best solution was to call or contact Brasseur and ask.
When I did, Brasseur kindly told me that the chip was missing from the items they'd sent me. Within days, they sent me the right whistle boards and all is okay. This is a neat little whistle and the price is great.
I just wanted to thank everyone who responded to my call for help. I included a picture of the "inoperable" 691-AMDK-074 whistle board (K-Line, I think). You can clearly see where the missing chip should sit on the board.
Thanks!
