SO, a couple days ago, I accidentally smashed out my rear window. I just got a new one and it has a defroster built into it. My previous window didn't have one on it, so I don't have wiring going back there right now. Does anyone know what I need to do to get it to work? How about just a plain old toggle switch that'll run it straight from the battery? Fuse rating? I've never done this before, and I definitely knew this is the place to ask.
