Mentions of soy in wiring. When my FIL passed away during the pandemic, I had been furloughed and was bored.
His Ford Escape had been parked in the driveway in their farm community for years and had largely been consumed by mice. I had nothing better to do so I took on the car as a project to get it cleaned up and see if I could sell it.
Mice had covered the engine in snail shells. Eaten the hood insulation and stuffed the hvac vent tubes with it. Built their homes in the kick panels.
Gutted the interior, cleaned everything and put it back together. One of the oddest things was that all of the light grey wires had been eaten, killing the wipers, signals and other various functions.
Turns out Ford was using soy-based insulation in light grey wires.
