After seeing PetreeLX's recent disaster I decided to take steps to protect those wires going to the brake unit on my LC. I've had issues with mice making nests under the intake manifold in the past and now there is new squirrel nest in the tree directly over my LC. I expect hungry new babies will be crawling around in the coming weeks.
So, here is what I did and I think it will be pretty effective. I happened to have these materials on hand but aluminum window screen would work just fine too.
1st pic, screen cut to cover the plugs and wires and then crumpled to fit closely. This happens to be some very fine expanded aluminum mesh I had from a previous project. Aluminum works well since it holds it shape after forming.

2nd and 3rd pics: More of the same material rolled and compressed slightly to fill the void and add further protection.

Final layer. This is stainless steel screen which I folder and hemmed the edges on. This is much heavier duty than window screen but like I said, window screen would probably suffice as well.
To help prevent the rascals from trying to tear it off I put a long wire tie around the whole bundle to hold it down.

I did this all in about half an hour, very easy. Cut patterns out of stiff paper to test fit the pieces.
As a side note, I've found that fluid film sprayed heavily under the intake manifold has been a great deterant from nest building. I guess it's to messy for them. It stays as kind of a puddle under there - forever. And no, no smell isues at all.
 
I want to hear the story behind the yellow wrench! :)
 
Are you able to spray the fluid film into the cavity with out having to remove the intake?
And is there anything we don't want to coat underneath there?

Yes, the yellow wrench story.....
Had a Ford van once. The alternator caught on fire one morning on the way to work. The only way to stop it was to remove one of the battery cables, and guess what, no tools with me. LUCKILY I was able to wrestle one of the cables off by hand and dump some water on the alternator to put the flames out. I was very lucky THAT time but will never be without a way to quickly remove a battery cable in an emergency again.
Almost lost my van and all of my windsurfing equipment that time.
I also have present a few small pieces of rope looped around a hose, out of view in the pics, to tie a removed battery cable out of the way to keep it isolated once removed.

Yes, there are openings between the vertical runners on each side of the plenum and in the front where you can spray directly into the valley, and no, there is nothing to be concerned about spraying in there, at least in early 100's.
If you have a later model with the blower in there it may not be a good idea, not really sure how that system works. If it is a sealed system then probably okay.
 
I have an 2005 with out the Vvti, so I should be good. Thanks for the suggestion.

Actually, I believe it is the secondary air injection pump system (SAIS) that my be effected by fluid film. Or, maybe not, no idea how it works. Do your own research if you happen to have that system.
 
Some moth balls for good measure? Many think myth. Buy a bright LED in the engine bay also works well
