Can't wait to see it in color either. A thought on using spare wire from tail light harness...will the gauge wire support the electrical load? Might consider new wiring to eliminate possible/potential issue and provide piece of mind. You can hide the new wiring. Had another thought for your OD on/off switch...what about a foot switch (similar to a dimmer hi/lo) you could wire to a small red LED that'll illuminate when not in OD. Just thoughts. Love the build.
