I am trying to connect Sharepoint 2013 to Salesforce using OOTB functionallity.

Specifically, I'd like to create an External Content Type using a Business Connectfivtiy Services (BCS) Connection.

There are a couple of great YouTube videos that demonstrate this functionallity but they don't go into the detail of configuring the actual connection.

Has anyone done this type of integration before?  Any guidance would be greatly appreciated!
Thanks
