you will have a coil, if you're unsure follow the coil lead from the dizzy. then the wire you need is the black one. to check it (cos there are two wires) turn on the ignition and check the voltage of the other(might be red or somthing) wire (i.e earth probe of multimeter to a ground point, other one to the terminal to be checked) you should have 12v or there abouts. if so theen connect your tach to the black wire and job should be done
