figureing out electrical additions

[the head]

I have three pieces that need ign signal in the car. four that need illumination in the car and one that needs Ign in the engine bay I plan on using relays on all circuts but i don't know which wire i should use for the relay actuation and i cant figure out the color coding in the wireing diags i have so to recap i need a low current ign wire under the dash (off when starter is running) to take one relay. A ill signal wire that can handle two relays and an ign wire by the passenger side relay box in the engine bay to handle one high current relay (on even when starter is running) any suggestions would be greatly appriciated
