PCM Fuse/Relay question or opinons ?

PCM Fuse/Relay question or opinons ?
After looking at the Pinouts, wiring diagrames and searching and reading threads... Question or more of asking opions...:
I have look and considering using one of the engine bay Fuse/Relay boxes from a 02 Z28....
I could keep is simeple and just use a few fuse and the Fan Relays..
Or Should I go hog wide on duplicating many of the OEM fuses and setup.. like Ign #1 & #2 (Coils), Injectors and anything else that was orginally Fused/relay as OEM ?
Sample drawing (many not be technically correct)
I know I could just do away with the large fuse and relay for the Ign and run it straight the Key / Ign switch..
Also. the Fuse / Relay box has three Fusable links that power the box. should I use them also and how many ?
Would I be safer doing more fuse and relay (protech and distribute load).. or just keep it simple.. ?!? (yeah.. sometime I think to much or have to much time to waste ?) ... What do you think ?
Thanks.

Well.. I've already hacked up and seperated the two fuse boxes, as I was only going to use one..
i will have to redo the harness to have the Pink Ign 12+ coming from the PCM to the Injectors and the Coil banks be routed to the fuse box and back into the harness now. I guess I will have to wait to do some of this, would need to complete the mounting of the PCM and the box before I can finish routing some of the wires.
ok. thanks, Any more opions ?

Ok. I reconfigured the Fuse Box to handle the following and usages.
Relays:
Fan Relays (2)
Fuel Pump Relay (1)
Ign Relay (to feed off of 12+ Battery to IGN/Pink wires.) (1)
Fuses:
1) PCM Battery 12+
2) PCM Ign 12+
3) Fuel Pump Relay
4) Fan Relay
5) Ign Bank #1
6) Ign Bank #2
7) Injectors
8) ODBII Connector
Large 40/50A fuse:
1) Fans Relay / Fuse
2) Open
3) Battery 12+
4) IGN Relay/Fuses
Now I just have to wait until I figure out where I will mount the PCM and the Box. Well also have find the correct wires for the Injectors and Ign/Coil wires to route them to the Fuse Box.
