I did do some preliminary research into this mod....
The outer tail assemblies (stamped into the rear 1/4's, are the same between 2010 - 2014 model years.
The difference between '10-'12 years, and the 2013+ tails, is that the inner assemblies (located on the trunk lid itself) is what is different.
So an entirely new trunk lid from 2013/2014 would be req'd to purchase, in addition to the ENTIRE outer/inner tail assemblies.
Wiring schematics are different, and do require altering.
There's a "How-To" thread write up somewhere, albeit on/in another Taurus community. I'll have to go digging for it, and post a link here.
I believe the trunk lids alone (minus the tail assemblies) was in the range of $1,100 to $1,300. Didn't include paint.
So begin to start factoring in prep, paint, removal of old trunk lid, install of new one, then the price of the tail assemblies, as well as the wiring changes, it is a fairly pricey retrofit, to say the least.
