[Plugin: iCal for Events Calendar] iCal Events Plugin

I’m trying to install the Ical event calender plug-in. I uploaded the ical-events.php and import_ical.php to the plug-ins folder (wp-content/plugins), and activated the plug-in, but that’s where I need help. According to the instructions I need to place this script:

<?php ICalEvents::display_events(‘url=http://www.ufl.edu/calendar/ufCalendar.ics&limit=3&gmt_start=’ . time()); ?>

…in the template. Exactly which template and where in the template.

Here is the link where I got my installation instructions:
ICal Events Calender

Here is the author’s site that created the plug-in:
https://dev.webadmin.ufl.edu/~dwc/2005/03/10/ical-events-plugin/

Here is the section of the site I would like to have the calender at:
http://thetequilaman.info/events/

I would be very helpful if someone can lend me a hand.

Thanks,
David
