SPARK PLUG CABLES
GENERAL
Resistor-type high-tension spark plug cables have a carbon-
impregnated fabric core (instead of solid wire) for radio noise
suppression and improved reliability of electronic compo-
nents. Use the exact replacement cable for best results.

CAUTION
When disconnecting each spark plug cable from its
spark plug terminal, always grasp and pull on the rubber
boot at the end of the cable assembly (as close as possi-
ble to the spark plug terminal). Do not pull on the cable
portion itself. Pulling on the cable will damage the
cable’s carbon core.

3.
Check spark plug cable resistance with an ohmmeter.
Resistance must be 1625-3796 ohms for 6-1/2 in. (165
mm) cable, and 5000-11,680 ohms for 20 in. (508 mm)
cable. Replace cables that do not meet resistance speci-
fications.

INSTALLATION
Connect spark plug cables to ignition coil and spark plugs.
Make sure boots/caps are secured properly; this will provide
the necessary moisture-proof environment for the ignition coil
and spark plug terminals.
