2001 Nissan maxima Side Mirror?

I want to install an M3 style side mirror with LED, the problem is that the OEM mirror only has the power window function without the light. There are only three wires that go into the OEM mirroe but I need four wire or something that will ignite the blinker light. Is there any other way to go about installing it please tell me and be specific. i have looked around on maxima.org and no results.
