Spark Plug Wire: Description and Operation
SECONDARY WIRING
Spark Plug Wires
The secondary (spark plug) wiring used with the ignition system withstands very high temperatures, thus providing an excellent insulator for the
high voltages generated by the Ignition Control (IC) system.
Spark Plug Boots
The spark plug boot forms a tight seal on the spark plug. The boot should always be twisted one-half turn before removing the secondary wire
from the spark plug.
