Does this help?

<?php  

  if ((USE_CACHE == 'true') && empty($SID)) {
    echo tep_cache_categories_box();

	// This appears to be a point in the code to show
	// boxes for users that are not logged in yet.
	// You can add the new box below if you want it to 
	// only show to users who are not logged in.


  } else {
    include(DIR_WS_BOXES . 'categories.php');

	// This point in the code shows categories when
	// users are logged in. If you want your new box
	// to show only to logged users, add it below.


  }

	// if you want your new box to show all the time, add it below

?>
