There is another solution to rodent damage, Mouse Blocker(might be called something else in the US). I work at an Auto dealership in an area with lots of rural properties, and we sell a ton of these. Its a small unit that attaches to the battery and emits a very high pitched squeal, above the hearing threshold of most people LOL.. But it does work and I have heard from many of my clients that their rodent problem has vanished. Worth a look , considering the cost of repairing a harness these days. They run around $100.00 and are very easy to install..
