Ignition wiring

is there a safe way to protect the wiring from rodents or pests on a car always parked outdoors

Pepper sauce.

Right…Paint the wiring with Tobasco sauce…

We have lived in the middle of nowhere for 35 years & never have had a problem with critters eating the wiring in our cars.

They have used our air cleaners for storage. Nothing better than the smell of roasting acorns @ 65MPH!
