Recently I noticed some rat droppings on top of my engine (car parked outside) & some damage to the wiring cover
as shown in the picture.
Soy based wire insulation damage by rodents has been in the news lately affecting several car brands.
Not sure if Nissan uses this insulation?
The wires themselves look OK just the plastic wire covering which I taped up with more electrical tape.
I read somewhere that if you are storing a vehicle put a bar of Irish Spring soap under the hood, the rats hate the smell.
So I decided what the heck & installed one.
