Primary Power Busbar use with upgrades

[Aussie]

So I am currently doing upgrades to my 72 C10, with a Holley Terminator fuel injection is first, then electric fans and Vintage air to follow. I believe these will all require a direct primary power feed. The pick up already has headlight wiring upgrade that has a direct feed from battery. If I have this correct I need a minimum of 4 primary feed sources, and was thinking of using the Bussmann LMI series, https://www.eaton.com/Eaton/Products...ries/index.htm to try and keep as tidy and effective as possible.

I am not very versed in auto electrics, so wondering if I am on the right track? Is there a better solution. How best to handle relays? Are there other items that will benefit from a direct power source, eg: fuel pump (Boyd Welding Aeromotive Stealth 340 In-Tank pump).
