Create custom Connector for Salesforce

[brendafos]

With the previous version of Alteryx I had created custom Salesforce Input and Output connectors.  They stored the connection details and made my Salesforce work go faster.

Now I'm trying to do the same thing with the 2018.3 Designer.

I've downloaded the new versions of the Salesforce Input and Output from Gallery.  

And I've made a new directory to hold the new Output - and then I've hard coded the connection details into the GUI.HTML and fixed the paths to the parts. And I made a custom .png icon file.

But the custom connector is not showing up in the Connectors  - what is different from the previous way this worked?

How can I make the custom connector who up in the tools?

Thanks

I've got a new custom Salesforce input tool showing up but for some reason I'm having trouble on where to hardcode my information in the connector. Any chance I can get some help on that part?
