Shift light help

[Cap_D]

I bough an MSD shift light. It has 3 wires. 1 black for ground, 1 red for power. and 1 green to hook it up to a signal. I have an 98 EK ~ EX and I am wondering which wire and were would I splice into for the tach signal to make the shift light work.

I did a test and the light does work.

the signal would be the negative on the coil,that's where you get the tach signal,as for the colour,I have no clue sorry

its the blue wire, i just looked at my car and thats where i hooked up the signal for the tach

if you hook just a shift light to that its either not gonna work or it will be on all the time. you need an rpm activated switch. kinda like an ignition switch that turns power on at a given rpm.

well it comes with chips, and I choose the cip with 6900 rpm, so the blue wire coming out of the distributor?

Blue one is your tach signal
