Share custom module content items between several instances

I have similar module that I want to share between several sitefinity instances. Module was created based on Products example.

I created separate database that I want to be shared. Added second connection string. Configured default module's provider to use separate DB (I did it before installation, because I want tables created in the other database). Installed module (in InitializeDefaultProviders). After installation, I verified that tables where created in the separate DB, but I don't see backed pages for the module administration.

I'm I missing something?

PS: If I don't use provider pointed to the second DB the module is installed correctly. But I want my module's data tables reside on the second database.
