As you can see from the pictures and information at the beginning, no adding the blinkers is not plug & play but rather splice & solder. The wiring is there for it but you apparently have to tap it, that is why he is saying to use 18" pieces of wiring. But it appears that the connector from the door to the mirror transfers all the voltages into the mirror assembly. But then again I am under the impression that it is there on the 2010 but unclear if there for 2011 and above. If you want to add power fold, extend/retract then you need to pull additional wiring. Ford has indeed made it confusing, but then again they shoot themselves in the foot by not only not prewiring for those of us that want to add later on but they are also pricing themselves out of the market for the addons. Oh, well whole nother subject.
Waited this long, am waiting just a tad longer to see what A1 addons are about and their pricing strategy is going to be.
