For the blue light function,your first choice is to connect with the puddle light power if you have. Or you connect with the side mirror flip power. If you don't have all these two function,then you have to open the door panel to connect with the positive to get power,it is a little bit complicated. Anyway,you can just use tape to pack it and let it be or cut the green wires off ,use the yellow turn signal only. 1.Please check our pictures to ensure ours match with the wing mirror on your vehicle. 2.Please allow slight manual measurement deviation for the data.
