Thread: RPM Tach

  1. #1

    Default RPM Tach

    Finally got my truck running and I am trying to adjust the idle of my truck, but my rpm tach is not working. If I hit a bump in the road it will sometimes come back on. Obviously there is some sort of short in the wire. Does anyone know which wire ( I need to color ) goes to the tach??
