Each itinerary service shape that you drop into the design surface has a Tracking Enabled property. When it´s set to true, every time that itinerary service is executed, it´s execution will be traced into BAM, so we will be able to create views and reports on the execution of our itineraries.

Yes, the connector is just meant to link the itinerary model elements to each other.
