Mirror Signals

[TJNE]

I have towing mirrors (Kool Vue aftermarket) on my 07 classic that I would like to add LED signal lights to, what I dont know is the color of the wire that I need to connect to. Does anyone know? I can pull the door and test but I figured maybe I could skip some steps if someone could tell me. Thanks.

I figured it out ,thanks anyway.

P.S. their are seperate fuses for the left and right turn signals....bet you can't figure out how I know that.
