I know a lot of you guys wired it to the fuse box but i found i would just splice in with the home link mirror wire. Now for you guys who did this, which wires did you hook up with which ? There are 4 wires (black,red,yellow, and green if i remember right) for the wire for the V1 and the power cord to the mirror has 3 of them. I tried to put together the black and red , and then the yellow and green and wired them to two of these 3 wires. My V1 powered up but when i go to change modes it does nothing, it is like it is frozen or something. I checked with the regular cord and cigarette lighter and my V1 works changes mode fine. So it must that my set up is wrong. Can u any of guys help me ????

 

i got it guys, it is green and red wire.
