I'm not familiar with that tach, but I wonder if you can wrap that pickup wire to one of the coils??? I just connected my Acewell 3200 tach/temp guage to my Twin Peaks (aka Prairie) yesterday and this tach had 2 options...connect it to the CDI (such as my Dyna programmable CDI or a VDI), or wrap the pickup wire around one of the coil wires.
Good luck with that and happy trails...
