Wiring up heated mirrors from 3rd gen maxima

[ze12o]

Quick easy question that I cannot find the answer to for the life of me.

I have the blue polarized mirrors from a 3rd gen max and it has a defroster pad. There are two wires which I have no idea which is negative or positive. The maxima's FSM is unclear (to me at least)

So my question is
Is it as simple as ground one and a switched +12v on the other?

I have the Kouki 180 Heated Power folding mirror switch. I have one wire left and I'm ASSUMING it is for the heated mirror (Already wired up power mirrors and PF option).
I don't know what is coming out of that wire since I've fried the switch and I'm waiting on the replacement switch. Will check with the multimeter after I solder the new switch in.

Any input will be appreciated
Thanks in advance.

While not a 100% answer, I know on the 4th Gen Maxima's it's a power wire (via the defrost button) and a ground. With that said I can't tell you if that power wire requires a relay, or is just a switched 12v.

yeah,...fsm im trial and error. But u run the risk of frying more switches and such.

hope someone has an answer!
