Doesn't matter just make sure that all ten are connected, i usually have a certain way of doing it as you have to have it turned a certain way for the length of the cords to work properly as it sits next to the miner, usually with the plug outlet facing the front and on same side as the control board plugin.

It does matter which way they snap in though, notice a little clip like thing on one side, you have to match those with the miner, when done right they will snap in place and then you have to squeeze them to get it to release.
