By "connect remotely" I'm not sure if you mean SQL Server access from a different machine or remote desktop to the host, but I'll address the former. If you are using SQL Server 2012 AlwaysOn Availability Group, you can connect directly to a given SQL instance or connect to the current primary through the listener name or address and port.
You should be able to 1. Open SQL Server Management Studio 2. Select the SQL Server (Cluster) Name from the [Server name:] drop down 3. If Cluster is not in the list, you can either type it in or browse for it 4. Choose Authentication type (Windows Authentication or SQL Server Authentication) 5. Enter your credentials (if SQL Server Authentication is selected) 6. and click connect
