I still have no idea how someone could be so grossly incompetent as to spec out a wiring insulation that won't hold up to the heat in the engine compartment.
You'd think that if the engineer at Ford didn't have a clue, he/she could have called the wire/cable vendor and asked, "Hey, like, dude, what kind of wire are you like, supposed to use for, like, dude, underhood applications?"
