Included is both halves of the Molex connector with four wiring pins and a sixteen inch piece of fire sleeve to protect the wiring leads. All the racer has to do is crimp the terminals and cut the fire sleeve to desired length.
Barrel type crimpers must be used to properly crimp the terminals. If the racer needs the proper crimper RBS can supply barrel type crimper jaws that fit into the MSD spark plug wire pliers at an additional cost.
