2017 Hino 268A - Cab+B Fuse issue

I need the wiring diagram from the fuse box, specifically the Cab+B fuse.

I have a truck with what appears to be a "parasitic battery drain". It was drawing upwards of 1.5 amps, but jumps around a lot. The biggest culprit was the dash cam/gps. When I eliminate these, it drops down to about .15-.33 amps. The next culprit is the Cab+B fuse, which then gets it down to about .06 amps when that is removed. I can't find a wire diagram/schematic to tell me what this fuse powers. The dealership said they don't have it either, but I don't even know where to buy something like that. Does anyone have a diagram/schematic that they would be willing to upload? Any help is appreciated.

Go to Hino.com.

Click on "Parts and Service" at the top, then "Publications"

On the landing page click on "Body Builder Books"

On the next page choose "Body Builder Guides". Its a free download. Chapter 7 has extensive electrical diagrams and information.

I was able to use it to do a complete Remote Start Install. Found absolutely everything I needed down to the plug and pin number.
