Esentially, it uses the factory fuel pump wire to trigger the relay, and through the relay you run a 10gauge wire wich ties directly off the battery for more power. The original factory fuel pump wire is very small and under heavy prolonged loads of power the ecu will put the fuel pump in limp mode showing too high of an amperage draw. You can buy the rely kit from summitt for cheap or you can make your own.
