NGK 7mm Sparkplug Cable Splicer
Description: For those using a sealed CDI system, NGK has developed a water resistant cable splicer to connect NGK Racing Cables to the stock ignition system. Simply insert each cable into the splicer, tighten, and you are ready to go. When used in conjunction with the NGK Cable Splicer, NGK Racing Cables can save you the significant expense of replacing entire ignition systems simply because of a failed cable.
worked for me but i cut mine off out from the coil, not directly off of it so I'm not sure, i think you can get the coil open and rewire a new wire to it, at least i think i read about doing that somewhere
