Serpentine belt routing??!

[MyFirstDiesel]

Okay so I have the upper shroud off and am trying to rout this new belt and it seems as if the diagram on my truck shows that it has one extra pulley than it actually does. It is a single alternator truck. Any thoughts? Or tips on how to re rout this and/or other diagrams? Thanks

The extra pulley that you are seeing in the picture on the truck is for if you have duel alternators on the truck. If you don't, you would follow the dotted line on the diagram.
