Hello,
AutoZone has some great diagrams online free of charge.  Try this link: http://www.autozone.com/servlet/UiBroker?ForwardPage=/az/cds/en_us/0900823d/80/16/3f/b5/0900823d80163fb5.jsp.  If that doesn't work, go to their size (http://www.autozone.com) and click "Repair Info" in the left menu.  It will ask for your car.  Put in the information, and voila!  All the wiring diagrams you need (well, click through to "electrical" first, but you get the picture...)
Best of luck!
