If you look through the install instructions for the PCV (not the AT), you'll notice in one of the pictures that there is an arrow that says "12V Auto Tune" on it. At the very end of the PCV instructions it tells you that the 12V source for the Auto Tune is the Pink wire in the accessory plug shown in that picture. It seems silly that they put this information in the PCV instructions rather than in the AT instructions, but I guess that's because the AT used on our bikes is a generic model as opposed to being brand/model specific.
