Wiring diagram for a walthers SW8/900/9/1200 QSI Decoder

Greetings! Does anyone have a wiring diagram for a QSI 187-2v7-42-2 sound decoder? This is the one that comes factory installed on the Walthers SW8/900/9/1200 switchers. If anyone can tell me where the wires from the two plugs go it would be greatly appreciated. Thanks.

Hroth7,

I spent a liitle time searching and I can’t even find that decoder. I would only be guessing, without seeing it. Lights/Speaker?

My suggestion: Give Walthers CS Tech a call, not e-mail, faster response:

While not a diagram, a couple of years back there were two or three You-Tube videos on installing decoders in those engines. They may still be there.
