Help with Tach install!
 

Putting a tach into my civic... 97 HB DX. Its a small 2" one, we can get everything to work except the RPM's, it lights up it powers on, all that good stuff. The wire we tapped into for rpms "green one" was in the back of my cluster it is a blue with black stripe wire... Is this correct? Any easier thoguhts? THANKS :yes:

i thought you usually have to connect it to the positive wire of the coil, which has more like a sinusoidal signal, not a square type signal like the usual clusters have. well i hope i know what i am talking about lol
