Thanks man I booked marked it.You might want to check this out. I had a friend nearby who had ground squirrels chew the harness on his Tundra and the mechanic who repaired it recommended this product. No problems since he installed it several years ago. Seems to work on other rodents besides pack rats.
I wouldn't use anything nasty like bleach and even ammonia is hard on plastics.
Find a juice called "Rodent Defense" check the usual ripoffs on line, Amazon and the like. Stuff works, not overly noxious. Ask me how I know, I have a Tacoma and had a dined upon WRX.
