The distribution box contains a coil
The coil is responsible for generating high voltage electricity, which is then sent to the distributor. The distributor contains a rotor that spins inside it, distributing the voltage to the correct spark plug at the right time. This sparks the fuel and air mixture in the combustion chamber. The main components include the ignition coil, distributor cap, rotor, spark plug wires, and spark plugs. The ignition coil plays a pivotal. Some distributors, such as HEI systems, have the coil in the distributor cap. Here's how to go about this wiring process.
