> Using one kind of unkeyed connector in a car may be a bad idea. Things can be plugged in wrong during repairs. I tried to lower the window in a Ford shortly after leaving the dealer. It fried the lock. Somehow they were connected together by accident. I agree dumb wires should be hard to mix up like that - both via orientation and similarity.
