2005-2015 Turn Signal Mirrors

Hey guys, new here. I have a 2012 Toyota Tacoma TRD Off-Road, and I recently added 05-15 turn signal mirrors. My truck did not come with them from factory, and I've been looking everywhere for MONTHS on how to make them work. Power to the mirrors is working because I can adjust them with the controls, but I cannot figure out a way to get the signals to work. And I cannot find anywhere online to locate the wiring harness as well. Does anyone have any ideas or know anything about this problem, or where to start? Thanks.
