Eurocom 780 connector to HDPlex 400

[Vocaloholic]

Hey guys, im building a 1080ti / i9 9900k build and im not really sure which wires i would splice to the female g16 4-pin connector to the hdplex. The power supply wiring is the only part where im a little confused and would like to see if anyone would be able to help me out.

Do you have a multimeter? I would start by using a multimeter to figure out which wires are which in the g16 connector on the eurocom.
