Using an external class from within an iRule is no different than using a "internal" class. You can use the findclass or matchclass methods to do lookups in those data groups. The only real difference is that external data groups are stored in files on the file system. They are mainly used for very large lists (ie, blacklist looksups) where management from the GUI's listboxes would be unusable.
What specifically were you looking for? If it's just how to use matchclass/findclass you should be able to find examples in the wiki.
