The Optifine emmisive format requires the Continuity mod to use if you're not using Optifine; ETF and EMF are only for the custom entity functionality

Continuity also adds the connected texture functionality
Emmisive textures are not applied directly to models, they are overlaid on top of textures of the same name without the "_e" suffix
There is no such thing as the "emmisive" texture field in a model, you can remove that line
I suspect your model is only the way it is to test and once you install Continuity you should see that the north, east, and west faces do indeed work
If not then you can send a picture here to show what you see instead
