I ordered a small led shift light, I cannot see, keep up with that tiny little tach when tucked in, maximum accelleration. I remember it has been discussed before but where is the easiest spot to pick up a coil pulse, or tach signal on the vrod? This particular light will read either both coil pulses or just one cylinder. Also, is there a readily available switched 12 volt pickup point too somewhere? like an accessory plug or something? I know you would have the answers right off the tip of your brain for me.......you smart guy. Thanks.
