2012 f 150 have the mirrors with turn signals in them. Power adjust. Have a chance to get tow mirrors no power or signals. My question is if i get these and just dont hook up my mirror signals will it screw up my other signals as in showing as one burnt out?

I think you'd be totally fine.. the fast flashing is based on reduced load, i.e. bulb burned out.... small light on the mirror draws basically no power compared to the incandescent bulbs in the rear (2) and parking light (1) on each side.

and I don't see ford having different "fast flash" thresholds based on the trim model of the truck.
