I have purchased a MRC Mini HO/N Synchronized Steam Sound Decoder (28 sound functions) When installing it - what do I do with the polarity switch that is already there?

Before you install it, find out the maximum voltage and amperage that the controller can handle.  On most HO/N engines the maximum voltage is around 12 volts.  Many "G" engines barely run at 12 volts and usually max out at 20 to 22 volts. 

Typical "G" engines draw more than 0.5 amps. 

You need to know if Thomas will burn out your controller.

As to your original question, I think that if you set it to NMRA, as that is the conventional standard, it should be OK.
