manufacturers name into the URL?

[mc12345678]

after install simple-seo-urls still i got mysite.com//index/manufacturers_id/12

To confirm, the page works, but it is desired to have it say/show a different uri?

Before installing the above suggested code, was there already a uri rewriter installed? Did it get removed as part of the process? I don't recall that the uri provided as a "problem" is a ZC standard URI.
