That is a great recommendation, Pavel. The wires from that plug should be pretty easy to get to, certainly way easier than the relay or fuse.
I am worried about the switch power rating. I suppose if I remember to only run one window at a time this would reduce the amperage but that's not a robust solution.
Perhaps the switch could engage a separate relay that serves to make the 10-3 bridge you are proposing?
