We keep a roll or two of Rodent Tape for these types of repairs. I'll repair a harness and then wrap it in this stuff. I think we order it from Honda?
I don't know how well it works, but I can't say that I have really seen many come-backs for rodents chewing through that stuff that I can recall?
Part # 4019-2317
Be thankful they didn't chew up the knock sensor harness, that's an annoying pain in the ass to replace without pulling a cylinder head off.
