Hello,

I'm installing a back up camera on my 2010 is250, and trying to tap into the back up light for the power source. When you see the picture, #1 is where the light is located, and i see 3 wires going into that light(#2). Anyone knows which line is the positive line? It seems like typical color is black but I see one green and 2 white, so confused.

Also any idea on what awg of this line? I'm trying to use t tap connector.
