in a recent post lucid suggested a modification of the permanent jumpering of the rsr. having reservations about having constant 12 volts fed to the injectors he suggests jumpering the relay energizing input to the relay main output thus feeding 12 volts to the injectors only when the engine is running ( i hope i have expressed this process correctly). my question relates to the size of these two wires. the relay energizing circuit is smaller than the main circuit served by the relay. is it big enough to carry the flow pulled by the injectors? also, what harm can be caused by a constant 12 volts to the injectors?

thanks, chris
