need your advice with my small electrical problem

each fan does have its own relay with a main power wire with their own 30amp fuse. the headlights has its own relay also.

i have the solenoid grounded to chassis and i have the ignition switch feeding power to the "s" terminal on solenoid when turned on. I believe all the main power wires are like a 10 or 12 awg wire.

I also have a solenoid for the starter. I have tried to put a relay for everything. only thing i dont have a relay for is radio and fuel pump but i do have an inertia switch for fuel pump and it doesn't draw that much amperage.
