Ignition Cable: Description and Operation

The spark plug wiring used with the ignition system is a carbon impregnated cord conductor encased in a 7 mm (9 / 32 in.) diameter silicone rubber jacket. The silicone wiring will withstand very high temperatures and also provides an excellent insulator for the higher voltage of the ignition system. The silicone spark plug boots form a tight seal on the plug and the boot should be twisted 1 / 2 turn while removing. Care should also be exercised when connecting a timing light or other pick-up equipment. Do not force anything between the boot and wiring, or through the silicone jacket. Connections should be made in parallel using an adapter. DO NOT pull on the wire to remove. Pull on the boot, or use a tool designed for this purpose.
