I'm installing some M3 Mirrors for my gf and I was wondering if anyone could tell me how to get to the power supply for the turn signals. I already have all of the power for the movements of the mirror connected, but I can't get the lights to light up when I turn on the signal lights. If anyone can let me know a way to tap into the firewall or turn signal connection, please let me know the quickest and easiest way to do it. Your help is greatly appreciated. Thanks.

 

You should run another wire from the side mirrors and connect it to your turn signals

 

that's how i wired my sidemarkers.
