What is an Ignition Lock Cylinder?
The ignition lock cylinder is the cylindrical tumbler and key that is used to power on and start your Mustang. Most ignition lock cylinders operate in different positions when the key is turned. The first turn usually unlocks the steering wheel, the second and third turns power on accessories and the vehicle's PCM if equipped, and the last turn cranks the engine.
The ignition lock cylinder is a mechanical component and has no bearing on electrical distribution other than when it actuates the ignition switch. With that being, if you are experiencing electrical issues or no-start concerns, I would take a look at the ignition switch and its associated connector instead.
