I installed the Trail Tech Vapor computer on my bike but the instructions say to splice power from the stator with no clear instructions as to which wire. From my understanding you only need power for the backlight. I have everything else hooked up (temp, rpm, speed) and everything works. I'd like to have the power connected too for the backlight but I'm not sure how to go about it. So what color stator wire do I splice into? Any preferable ground spot? Thanks for the help.
