I reached out to 45HomeLab when I was building my HL8 and they actually provided me the files for a 3D printed jig to crimp the PSU wires into the low profile yellow molex connectors. You can see it in the pictures from the post linked below. It calls out orientation of the PSU along with the red and yellow wires. There’s a keyed spot for the standard molex connector so it’s practically mistake proof. I know not everyone has a 3D printer so this is probably something that should be offered and sent with any PSU warranty work. @Vikram-45HomeLab
Hopefully nothing was damaged if you did cross the wires. A multimeter can also help you identify which wire is which.
