Hi Tracy whaley, I want to help you with your question, but I need more information from you. Can you please add details in the comment box?
These newer cars and trucks have multiple diagrams for all different kinds of components under the hood. Could you be more specific in what you're asking for or maybe you could go to the local auto parts store and buy the repair manual for the car for about $25.00
