Featured Listings Random posts

Hellow, im having an issue here in this website http://www.psicologiavenezuela.net/

As you can see im using a plugin called “Features Listing” in the column that has a header wich says “Profesionales Destacados”.

I have managed to modify this plugin so everytime the page refreshes the posts in the featured listing are random but, now i want to use jquery to refresh this posts every 10 seconds and i cant find where to start. I know that first i have to register my script so wordpress can add it in my head section.

With jquery i can load a php file using ajax, this file is gonna populate my column with the posts from the database but, in order to do so, i need to select the div where the post are gonna be displayed.

the js code that i have to use to get this done is this: `<script type=”text/javascript”>
$(document).ready(function() {
$.ajaxSetup({ cache: false });
setInterval(function() {
$(‘#divToRefresh’).load(‘/path/to/your/php/file/’);
}, 3000);
});</script>`

I dont know how to manage this, is easy to explain it but in code i dont have idea where to use it, because i cant find the file where this featured listing pluging is being called to render the posts. Any suggestions or ideas on how to do this?
