30 amp is enough to run almost anything bob. If say you have 2 power hungry fans run 2 relays instead of 1. Same goes for headlights. 1 relay for low 1 for high. Fuel pump gets its own relay as well as any acessories such as amplifier or electric power xx motors.

Put your relays at the suckers. You would put your fan relays by the fans and you would put your power window relays under the dash by the door they are powering. Keeps 12 volts at the source and spreads out the relays so you dont have a book sized relay bank under the hood.
