You can set "Apache Configuration File" to "/usr/local/apache/conf/httpd.conf"
http://www.litespeedtech.com/docs/we...apacheConfFile

and "Apache port offset" to something like "1" or "2", restart server, you should be able to access your Apache sites at port "81" or "82", make sure that port is open on firewall.

All of your sites is still managed by Cpanel, you don't need to add any thing in LiteSpeed's web admin interface.
