Do not use fuses of higher amperage than those recommended above.
The following wiring harnesses are protected by a "fusible link" which is a special wire
incorporated in the circuit; ignition circuits (C-K-P models). and starter solenoid (pull-in
and hold) circuit (C-K models). Should an electrical overload occur, this wire is designed
to fail and prevent damage to the major harness.
