Included is both halves of the Molex connector with four wiring pins. All the racer has to do is crimp the terminals, install the male/female plugs, connect and you are ready for connection paradise.
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.
