I have a 15 Ecoboost w/Performance Package. I recently saw a 15 that had factory pony projector lights in the mirrors. Does anyone know if the wiring, connectors are the same or exists if I bought the mirrors from Ford? If its a question of buying a sub harness, to plug them in, then that would be ok too.

 

There's a good chance the wiring is all in there. On my 14, I have the basic mirrors (no heat, no projectors) and all I needed to do was buy the heated projector mirrors and bolt them on. No additional connectors or harness or anything was required.

You can always pop off the mirror cover inside and see what the connector looks like coming from the harness to the mirror. Compare to connector on cars that come stock with what you want.
