The hardest part of this installation requires modification of the decoder because the manufacturer put a big fat resistor right next to the 8-pin plug that interferes with the plug on the 58820 model LokSound 5 Micro that would have the correct connector.
The issue is that the orientation of Pin 1 (Orange) on the circuit board forces installation of the decoder such that the body of the connector and wires physicaly hit the resistor.
I did not spend a ton of time researching this but it looks like this would affect nearly every NMRA 8-pin (NEM652) decoder I offer.
