Driver's side mirror signal not working - '15 Persona

Hoping someone has the schematic for the wire harness under the driver's side of the dash. I installed the remote engine start last week and noticed this week that my signal indicator in the driver's side mirror is now not functioning. To be fair, the dealership did activate the system earlier this week, so I'm not sure if they knocked a wire loose or if I did. Most likely, I did. If you have an idea which wire (location/color) is for this, I'd love to know. Did a search and found info on the JDM powered signal mirror install, but that's not quite the same. Thanks!
