Nah. Fit the coil wire end by pressing the sharp point through the wire making sure that the point goes through the center so as to make good contact on the wire inside the insulation. Butt the end of the wire and insulation up against the coiled wire before pressing the sharp point through. With that done spray some WD40 on the narrow end of the boot and slide it over the coiled wire connector. Make sure that the coil is oriented correctly in the boot for the plug the fit. Easy.
