Does anyone have wiring diagrams for the fuse panel and power distribution box? I am hoping to use a few of the empty spots on them, but I would like to know what they are for before I go changing things around. Also, I have a position in the Power Distribution box for a light called "Quad Light" anyone have any idea on what light that is?

 

A pretty tall order, the manual has over 500 pages of wiring diagrams.
Suggest you buy a manual for your truck from-

Well worth the price, it will pay for itself the first time you do a simple repair yourself. Wiring diagrams change every year, the cheap one year fits all manuals aren't always correct.
