Add a module to a component , but not every of the component

Add a module to a component , but not every of the component

i'm working on a joomla 1.5 for a university project (when it started 2.5
wasn't out :D). What i'm trying to do is to assign a module to my custom
component , but not every page of it. The 2 different pages of my
component is a page that shows every product , but the other one needs an
id to work.
