No, it is not the fuse box diagram. Look in section six chassis electrical. At the end of the assembly and disassembly instructions for the various components covered, there are several pages of wiring diagrams covering both four and six cylinder trucks and pathfinders. I've been making a study of these diagrams due to the wonky electrical issue that I'm trying to chase down on my own truck. The VG30i Pathfinder and Hardbody truck share the same wiring diagram, and the label at the bottom of the diagram states that it is for both vehicles. There are two diagrams that deal with the electrical on our trucks. One will show three fuseable links across the top left near the battery, and a fourth tucked away in the mid-upper right side of the diagram. There is a second one a page or two (I'm at work right now, and cannot look up the exact page numbers) after that shows ONE fuseable link that goes to the alternator charging circuit. You'll need a magnifying glass to read the text for the component labels. If I can remember to by the time I get home from work, I'll look up the page numbers and post them.
