Hey, I'm currently trying to figure exactly which wires I need to tap into to install a line out converter. I've searched previous posts and cannot get a definite answer. I just picked a 21 trail boss custom 7in display standard 6 speakers non bose. I contacted crutchfield earlier today to see if they had a diagram. Unfortunately they have an incomplete one. This is what they told me The ground is white/black, the constant 12v is red/yellow, and the front left right door negative is light green/black which probably means that the positive is a solid green. Anyone have a definite answer on which wires are which?
