I can't make a phone call, but i'm sure someone else can if you'd prefer that. Here are the schematics for your car. The first attachment is everyting and is very large. I included it in case you needed it. The second schematic is the engine compartment schematic. Start with that one and see if you can find what your looking for in that one first.
