I could be wrong but connectors are ember components so you actually need to change your directory structure here to match a discourse ember structure as well. I would look at existing official or pavilion plugins for examples.
Then again if you are stuck on server side rendering because of ‘amp’ you may need a different approach closer to what you are already doing. However I’m not sure connectors work in that scenario? - I’m not your best advisor here and will open that up to the house. 
Connectors seem to also be supported for server side rendered erb files.
