Do you have a vehicle with a chewed-up wire harness? It’s probably the work of rodents, and if it is . . . Honda parts stock has just the thing to deal with it: Rodent-Deterrent Tape (P/N 4019-2317).
After repairing or replacing the harness, wrap some of that tape around the affected area. It’s got capsaicin, the stuff that puts the fire in a bowl of five-alarm chili. This should keep any critters from causing future problems.
