Full Car Rewire - layout and fuse box planning

I have another full car wire up to do and i am always looking for new and better equipment (and ways) to layout different setups.

A PDM system isn't in the budget for this job but i'm interested to see what setups others are using and how they are setting up their fuse boxes and relay boxes.

i'm most likely going to use 2 x Bussman 15300 series (one for EFI and one for vehicle) as i can't seem to find something that is big enough for both tasks or im finding fuse boxes that have way to many circuits.

I've attached a rough idea of how i was thinking of setting up the fuse boxes.

They each have 10 fuses and 5 micro relays.

I would still need to run 2 external changeover relays for the wiper circuitry and a high current relay for the thermo fan.

Thanks

I like the pre-populated boxes such as:

or

Happy medium to a CAN based PDM.
