so im planning on installing a kill switch, ive purchsed a 5A 1NO 1NC switch with a LED ring and am curious as if i could somehow either directly or another mean to be wired to my fuel injectors so show when they are actively firing thus plusing/showing me how much/often fuel is being injected into me engine..

there is 4 common coloured wires on each of my injectors, not sure if that is the positive or ground.. any thoughts on how this could be acheived..

thanks1
