My brother had a Toyota Taco pickup, maybe 8 years old. Superb truck, though it’s not in rough service. One day he fired it up and literally every dashboard warning lamp lit up. He took it in, turns out rats had munched the wiring harness. His ins wanted to total the truck! The dealer wantedk $8k to fix it, he found a better deal @ $5k which ins paid. But the good thing w/Toyota is he traded the truck with $6k for a brand new one.
The wiring insulation on newer vehicles is made from soybeans, great idea, rats and mice love it.
