14. The inside diameter of the ring terminal on the end of the Mustangs Unlimited charge lead is a bit too small to fit over the starter solenoid’s stud. Using a pair of locking pliers to secure the terminal, a step-style drill bit made quick work of opening up the inside of the terminal to the proper size. DO NOT hold the terminal with your bare hands, as a drill bit can catch the terminal and quickly injure you. This is also why we prefer the step-style drill bits, as they rarely “grab” the metal. Mount the ring terminal to the solenoid as shown and secure any wiring with tie wraps to the Mustang’s OE wiring.
