Spectrum two truck Heisler 81795

[Don Carter]

Does anyone have a schematic of the factory installed DCC board?
I"m trying to install a Phoneix sound card P8 in the Heisler
The number on the board is 403 or maybe 4103
I need to know the use of the screw down lugs 1-12
such as power and chuf,
thanks, Don
