Where are the fuses?

About a month or so ago, my company assigned me a 2015 Pete. I like the machine except for one thing the previous driver did...he left me with very few functioning 12vdc outlets. I'm sure it's a fuse thing but the schematic on the fuse box cover is unintelligible and there is no indication of "12v" anything.

So, wise readers, where are the fuses? I don't get to any of our shops often and really would love to make these outlets work so I don't have to drag extension cords all over the truck.

 

I found one fuse panel on the driver side near the clutch; I'm still looking for others.

Maybe I wasn't clear enough on the "where are the fuses?" thing.

Not only am I looking for the fuse panel, but more importantly, I am trying to figure out which fuses power the 12 vDC receptacles. that's the partner the diagram this is incomprehensible...none of the fuses have anything remotely related to "12 vDC" on them and the Peterbilt owner manual is of no help.

Right now, I only have one of about a dozen or so that works. I cannot afford to lose it.
