2010 F150 does anyone know if the wiring for the mirror blinker or heated miroor is there on the xlt that does not currently have these options?

Thank You

 

I put a set of tow mirrors on my 09 XLT a couple of weeks ago. My XLT mirrors didn't have the blinkers, heat, etc. The blinkers work, however the puddle lights don't work (don't really care about that) and of course my truck doesn't have the rear defroster so the heat don't work either. I read somewhere that the heated mirrors work when you turn on the rear defroster. I think the mirror power plugs are all the same.

 

Had trailer tows put on my xlt everything works even the puddle lamps
