Ignition Cable: Description and Operation
SPARK PLUG CABLES
Spark plug cables are sometimes referred to as secondary ignition wires. These cables transfer electrical current from the ignition coil and
distributor, to individual spark plugs at each cylinder. The resistive spark plug cables are of nonmetallic construction. The cables provide
suppression of radio frequency emissions from the ignition system.
