I bought the Yamaha Hour meter and am a little confused on how to install it. I have mounted it fine but am a little confused on the wiring. From the directions it appears that I don't have to strip any of the wires, is this correct? The other question is how you attach the wire to the spark plug wire. Since the spark plug cap is a plug in type on top of the cap which wire do I wrap it around to make it work ? Should I wrap it around down by the cap or up higher?
