So, I’m an advocate for electrical heating lately, and so one natural outcome is to finally hook up my windshield defogger. To that end, I picked up a 200W defroster for cars. As you can see here, I’ve made a foam plug to layup a transition from the device to SCAT ducting (I already had the outlet molded onto my glare shield, I just hadn’t hooked it up). This bad boy is going to need a 20A breaker. I’ve picked up three Carling off-on-on illuminated switches to run the defogger and heaters for pilot and copilot. They go green for low heat (or fan for the defogger), and orange for high.
