so take a look at the following link:

There are two different diagrams here and which one you should be referencing depends upon whether your's is a "California" or "Federal" car.

Take a look at and even print both of these out and then take a hard look at each and you should be able to easily determine which car you have by the extra components on the California cars. I hope your's is a "Federal" car.

Let us know what you come up with!
