[TYPO3-mvc] Where to set the storagePID for Backend Modules?

[g4-lisz at tonarchiv.ch]

hi there,

from extension builder we made a backend plugin for our domain model...

there are the settings in ext/myextension/Configuration/TypoScript/*.txt 
- where can i make them read by the backend module?

the backend should be "idiot proof", there should be just one fixed 
storagePID for the plugin.

... maybe i'm the idiot at this moment...? ;)

cheers,
till
