Trying to hook up a shift light.
I have a 91 civic si with a DOHC ZC. I am trying to hook up this shift light. and I dont know where to hook it up so it will read the tach? where do I find this wire that I have to splice into?
Back of your cluster.
If you are sitting in the drivers seat look at the plug on the left. There's a blue wire, that's your RPM signal wire.
That's the easiest place to grab the signal, easier than getting it at the ECU or from under the hood.
