Thanks to all for all the posts on installing power folding mirrors. My 2013 F150 has memory function. All the wiring was at the plugs at the mirrors but my new mirrors would do everything but fold. I replaced the mirror control switch part#7L1Z17B676-AA $40.00 from Ford still did not work replaced DSM that's located under the drivers seat part#BB5Z-14C708A $200.00 from Ford $140.00 from Tasca everything works great. Just thought I would post this so someone would not have to read 20 pages of threads.

Thanks again,
