Check the PG section of the FSM. It has the wiring diagrams and pinouts. Nissan calls that fuse block the "FUSE BLOCK - JUNCTION BOX (J/B)".
As far as I can tell, the internal wiring is just a bunch of buses and there are no controls hidden internally.
I'm not sure where the power comes from for Fuses #3 and #4. Possibly the IPDM-E/R. It is in the wiring diagrams.
If you can't find what you need, let me know and I'll dig deeper.
