Anyone know the voltage that is applied to the heating element in the heated mirrors ?

I want to swap the heated mirrors into my Lightning but I need to know what voltage the heaters are, as well as what the connectors look like.

Any help would be appreciated...

 

Search "heated mirror" and "signal mirror" and you'll find a bunch of info. I am interested in installing both the heated mirror glass- wired through a 93 Explorer switch/relay/timer unit, and the mirror cover with the exterior mounted signal in it, on my '03 Screw. If anyone here has any additional info on either the heated OR the signal portion, please add it. BTW mine came with power if that makes any difference.
