Can anyone tell me what the extra electrical connector is for ?
a) heat mirror
b) the other connector is for ?

and
What is the part number (driver side) for a replacement glass ?

 

I have had my local Ford Parts Counter look up mirror glass PN by VIN.

 

There’s aftermarket glass all over Amazon much cheaper than oem if you don’t have heated mirrors

 

I'm in Europe so no Ford dealers that we can ask.
I did buy one from Amazon, it's missing the 2nd set of connections (flying lead with a small 2 pin connector as on the original).
and the Amazon one does not have such a good smooth reflection as the original.

 

Inner wires are for the Defrost the outside are for the Self Dimming Electrochromic part.
Part number should be 7L3Z-17K707-K

 

Perfecto.
Many thanks.

 

I just replaced my passenger side heated mirror for $15 from amazon. Installation was a breeze and it functions perfect.
