| This is Moto-P's 4AGZE ECU pin out from http://www.club4ag.com/ Tech Reference Section. I've reorganised the information to make it a bit more understandable for those playing with wiring. The "TOP OF THE ECU" refers to the side with the orange sticker which reads "4AGZE". It is also the side of the ECU which can be removed to reveal the circuit board inside! |
| Colour Scheme/Legend: 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. |
