School me on wiring

74 dart, 318, possibly using a /6 harness? Msd 6al, some kind of aftermarket fuel pump, havent decided yet. Factory lights and gauges, just the basic stuff to get the car running
Fuel pump is very basic, power supply from battery to relay. Power from relay to pump. Ground wires to chassis. Then a signal wire to relay. Either a 12v switch or a keyed hot. Msd box just as simple. Will have wire diagram on back of box.



Before you start anything google about relays and fuses. You are going to want to use relays and inline fuses when ever possible.
