Colour Scheme/Leged: R = Red, W = White, G = Green, B = Black, Blue = Blue, V = Violet (or blue), BR = Brown, LG = Light Green? What I call BLUE, Moto-P calls VIOLET. I could be wrong in my perception of the wire colour. Y-G means a yellow wire with green stripe. G-Y means a green wire with yellow stripe. No one is helping me out online here so don't blame me for any mistakes made as a result of this page. |
