Some of the electrical gurus can give better info than I can, but this is what I would use for both wipers and heater. Or this one if you need 25 amps. (Same info that I posted earlier re: 6v radios in 12v systems.) It's what I will use if I ever get my electric wipers working. I have a 12v motor in my heater so I don't need a voltage reducer for it.

That is a sweet looking '51 and a great family photo.
