Heatshrinkless double pin pci-e

[octime1]

Hey everyone. As the title states, I'm in tje process of heatshrinkless sleeving my PSU and ran into the problem of the double pins connected to my pci-e and some in the 24 pin. Ive tried to melt the fabric (paracord sleeves) to the wire and still havent gotten the sleeves to stay. Anyone have an idea as to how to do these without heatshrinks and preferably without that the pin apart and seperating them and then reassembling them? All four of my pcie connectors are 6+2 so would it be possible to take both black ground wires running to them and switch then with the doublepdoublepIn? Removing the dounle pin all together?
