Kill Switch with LED indication injector use/volts

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

I'd wire it to your oil pressure light. It turns on when the engine is off and it turns off when the engine is on.

No I think he means every time a cylinder fires he wants to see an LED blink.

If you got a circuit to do that, its not going to be very noticeable. At 1200 rpm, that LED is blinking 10 times per second. That is going to be barely noticeable. At RPMS above that, its not noticeable at all. It will grow brighter and dimmer, but thats all.

If you want to make it blink, you'd need to use some sort of computer control like an Arduino.

We can see more than 24 hz (babys can see 50)

You would be looking at flicker with frequency changing with rpm and brightness with injection time.
