Hi I'm new here and new to Honda's I just bought a 1993 civic dx a couple weeks ago and just yesterday I installed a tach because it doesn't have a factory one. After installing it now my blinkers don't work and none of my gauges move the gauge illumination light is still on and the hazards work still. For wireing the tach I tapped into the yellow accessory wire for the power and the cluster illumination wire for the light on the tach. I checked all my fuses but now I don't know what to do any help is appreciated thanks.
