Use at your own risk!!!
Note from Author of this schematic (NOT Xchoppers):
Please be aware of highlighted items (temp light and reserve light). When using the Diamond Digital and isolating the dash panel they will be eliminated. I do have a fix for this but I have not tried it out yet so I am wary of putting it out there. It calls for the use of resistors one wired in parallel the other wired in series (very important to know what your doing when wiring these two lights). I just left them alone for right now.
Also, it helps tremendously, to not use the speedo connector in the head light bucket. Instead, run a wire all the way to the back of the motor. The speed sensor plug is accessed by removing the left crank case cover and sub cover. It will be found in a protective rubber boot.
