Wiring help - Molex

Just need a quick confirmation here

According to this, if i was to wire it to a Molex plug from my PSU. I would wire the red wire from my molex cable to the DC 6v - 30v and then a ground wire from the molex cable to the ground on the furthest left point connector.

Is it as simple as that?

Yellow on a molex is 12v not red

Oh, so would i just use yellow and a black wire from the molex cable then to power this?

What are you trying to achieve?

Personally I would think the yellow 12v molex would go to the 4th pin (the +) and the black ground molex pin would go to the 3rd pin (the - pin)

Then you want pins 3+4 (the + and - pins) leave the 2 left pins unconnected
