I have removed the tachometer

I will install the leds under this

This is the inner ckt of my tachometer

The upper view

And here the actuall portion starts

there are two ports as u can see S+ and S- , and when i connect them to the multimeter at 1000v they throw the reading as
ooo3,0004 as per i rev the throttle I need your help!
and my bike is having 3 sparks plugs if i go with that method, do i need to regulate the output from spark plug or i can directly connect it to rpm wire of arduino?
