Sad 1995 Concorde News

I've kept my Concorde for winter bad weather use, saving my lovely 300M
from some abuse.
The Concorde is sitting beside my garage, beside a wooded ravine.
I run it up and keep the battery charged regularly.
About a month ago it started missing on one or two cylinders. It was my
intention to put the Concorde in my garage and look into this problem.
I was concerned it may be very difficult determining what causes the
miss.
Well now I'm not so concerned about the task of finding the miss cause,
I know what it is, it's too obvious. A few days ago I tried starting it
and no go, didn't even turn over. It seemed to be eating the battery
power with a clunk when I turned the key.
Looking under the hood, I was shocked at what I saw. About 8 small
exposed wires at the terminal block on the right side of the firewall,
had been chewed through, a few totally gone.

Dam it, how do I discourage some dumb rodent from lunching on my
Concorde's wiring?

 

Quit parking it in the woods? After all, that is where all the little chewy
critters live.

 

Put one of those rodent-deterrent frequency emitting devices under your
hood? I bought one (for my garage) for about $20 by Black and Decker.

Or do it the simple way of applying some anti-rodent goop on the wires?
