PSU Wiring question

[anomaly]

So I was going to flexo-pet my PSU wires, but my markings on the 2 black ground wires came off while I was doing the sleeving. I don't know which ground goes in the correct 4 pin molex, can anyone PLEASE help me?

I believe they are both connected to a common ground in the power supply so it shouldn't matter which one goes where. The two black wires are shorted together in the power supply.
