Chris,
That will work, but there is still a fuse in the line to the DA #1. It will work OK that way...it's just too much protection is all.
You have a fusible link going to block one from the BATT lug of the alternator, then, in the same line inches away, you have another fusible link.
You have to understand what these links and fuses are seeing and doing. Any protection in the same circuit will see the same load, so more than one fuse or link is redundant.
If you have a device that only pulls 7 amps, you don't need to wire it with 10 gauge wire which you will have to protect with a 30 amp fuse. The circuit should be designed from the device to the wire to the protection...in that order.
Fusible links will protect against catastrophic, dead shorts...boom! You're dead in the water until you can repair it.
Your diagrams are beautiful, but they have lots and lots of "things" in them...things that might not be necessary. It's your truck and doing what you want is the main thing. Make sure it makes sense from a electrical standpoint too.
