Hey Guy's I need help Identifying which wires go where I've searched the manual and all over the net but none of the colors match up to the one I have found. This is for a 2004 Chevrolet Silverado 2500 LS crew cab With Bose Audio. I marked wires in there placement so it would be easier to explain what go's where. I do know A-1 is 12v dc/hot and B-12/ground but I'm lost on the rest. I'm tring to install a after market Kenwood DPX530BT I have the diagram for it.it's just identifying these wires I'm having issues with. Any help would be appreciated. Thank's
