Ok, can you tell me which color wires dont have power while I am checking for the wiring schematic

A3 Black and white wire (low washer)
A4 Dark Green - (Speed)
A8 Dark Green white - trans shift
B4 Orange (Dic Mode)
B5 Dark Blue Dic toggle
B6 Dark Green white (Dic Switch)
B11 Orange (Battery positive volt)I'm guessing on the placements and what each color is used for...But the color of wire is what is not producing voltage
