Connecting with the instant client is no different than with the full stack client - all connect string formats are the same. If you installed the instant client in a non-standard location on the filesystem or are having problems connecting to the database listener, be sure that your TNS_ADMIN environment points to the directory that contains your tnsnames.ora and sqlnet.ora files,

The format is:
name/pass@//host:1521/instance
Standard Oracle connect strings typically look like
name/pass@tnsentry
Where tnsentry
has been defined by one of several means such as a tnsnames.ora
file. idstram's answer has an excellent pointer if you're looking for more details.
