I am totally lost trying to wire this after upgrading to the E3D V6. The video by Novice Expert is from the stand point of someone who knows what they are doing. The wiring video by Robo 3D, for the x, y, z says to reattach them how you labeled them when taking it apart. But how do I know which goes where if I didn't label it?? Also, the D9 use to go to a fan. Novice expert's video says to hook that back in, but it never shows putting back on any fan that might go to it? What goes there? Finally, I also accidentally disconnecte4d the Aux from the light on the side of the unit. The male plug has 2 rows of 4, the female has 2 rows of 5. Anyone know which way I plug it in??
