Need some help with wiring...
I´m going to make new engine wiring harness, but I don´t know what size of power supply wires should I use for ign coils, injectors, OMP and control solenoids (idle speed and boost).
I´m thinking about using 14 gauge wire for all of these. Will it work well?

14 gauge is fine as long as you feed each area item with its own wire. For example, don't feed both the coils and injectors from the same 14 gauge wire.

I thought I will supply each component with its own wire...
I have attached a wiring diagram, my conception is a 8 gauge wire into the main relay and 8 gauge wire into the fuel pump /ign coils relay. After the relays, each component has it´s own 14 gauge supply wire, each injector, each coil, OMP and control solenoids, except the fuel pump, which one will have a 12 gauge wire.

What do you think, will it work like this? Help me, please.

sounds ok, not sure you need such massive gauge wire for the main relay and fuel punp etc tho. 8 gauge is pretty big
