Seems like you would use both at the time. :dontknow:
Maybe you can just wire it into the rear window defrost.I got the mirrors folding by ghetto rigging the set up directly to my battery. Holy crap, I nearly froze my ass off just to test it out! Hooking up the mirror defroster is easy, I still have 3 pin plugs from my tail light rewire DIY that will take the 2 heater wire terminal joints from the USDM mirrors. So the final product will have 2 plugs on each mirror with a total of 7 connections.
Now the trick is to mount the heated mirror switch. I wan to retain the OEM switch so this will be a challenge to figure out. Worse case, I'll have to get an aftermarket LED push button switch to control the mirror defrosters.
