Help with M3 mirrors (wiring)

Hey, I bought some m3 mirrors and they didn't come with a wiring diagram. (They have blinker lights in the mirrors). I got them installed and on my car, but not wired up. You can choose between Blue and Green and I want to go with blue. My problem is that I have no idea where to wire them up. I can't find a wiring diagram or ne thing. I knwo how to wire stuff up, I just dont know where to wire it into. Ne help or advice would be GREATLY appreciated. Thanks.
