Advice on Setting up Salesforce Marketing Cloud Connector ?

I am trying to implement the Saelsforce Marketing Cloud Connector in a Cloud Integration map (Scribe).

I followed, as much as I could follow the Instructions contained here:, but was not sure what to enter for the URL - is it the SOAP Service Endpoint for the MC API User?  that is what I entered...  

when I test the connector, however, I get this error:

Connection test failed: An invalid security token was provided

There is an External Key generated for the MC API user - but I dont see where that can be used in the COnnector...  

anyone have this working that can advise me?

thanks in advance.
