I don't have any specific site to guide you to, but the basics work like this: The first character in the VIN is the country of origin (where the vehicle was built). 1= USA, 3= Mexico, and there are other codes for other countries. I believe that 2 is Canada, but don't remember too well. The next several characters describe the vehicle, by car line, trim level, and number of doors, and whether it is a 4-wheel drive or not (if applicable). Character number 8 is the engine designator, and the tenth digit is the year of manufacture. The year 2000 was designated by the letter "Y", and every year after is designated by a number (1=2001, 2=2002, etc). Everything after this character is the serial number, and occasionally uses a letter to designate the assembly plant. More specific information: Second character denotes make; 3rd character designates passenger car/truck, etc; 4th character denotes restraint system in a Chrysler; 5th character is vehicle line; 6th character is trim level; 7th is body style; in Chrysler, the 9th digit is a "check digit", basically a place holder; assembly plant is the 11th character, and the serial number constitutes the last 6 characters.
