I recently did a PC upgrade for a friend. We re-used his old PC case which I believe is an antec 1080 amg. There were two front panel cables left that I'm not sure where they go, because the usual front panel connections on the motherboard are full. The remaining cords are 2 pin connectors and one is labelled 1 and the other is labelled 2. His new motherboard is msi b450-a pro, would anyone happen to know what these 2 pin front panel connectors are for, and where they should be plugged into the motherboard?

Thank you!

The 1 and 2 connectors are for PCI harddisk controllers to indicate disk activity on them (bottom two LEDs on front panel).
Since you most likely don't have such an add-in card installed, 1 and 2 should be left disconnected.
