You carefully pare back the first two layers about 3/4" or so, try not to fray the cable at the core, then you fold the inner wire over the cable. You place the copper piece ovet that, insure that the solid part of the copper piece covers the wire and crimp in place. Oh make sure you put the boot over the wire first. You don't want to use the original wire since it was meant for point ignition and more than likely is pure copper cored. This supplied wire is probably an aramid fiber/silicon cored, carries electric impulse differently. Will.
