Alter this Simple Jquery Accordion Menu Code to Highlight Active Link p2

The attached zip file contains sample pages, jquery and style sheet. When one of the menu links, named service1, service2, serivce3, is clicked, it turns red for the active page. The other links remain black. This demonstrates the visual output I want to see. What I want is the logic that turns the link red, *NOT* to be hard coded in the individual pages, like how it is now. I want that logic to be built-into into the the CLIENT SIDE CODE such as css, javascript, or Jquery files because this code will be used on a site that has dynamicaly generated menus. This should be easy for a Jquery guru. I need this quick.
