Now for the moment of truth. The power switch. According to the dusty forum post he found from 2013, Pins 8 and 9 were the life of the party. But he didn't have the proprietary plastic housing anymore. He just had the raw wires from a standard case switch he’d scavenged from an old Gateway tower.

This is the most reliable method and requires only a small flathead screwdriver or a jumper.

Plug in the HDD LED (Pins 1 and 3) and Power LED (Pins 2 and 4). Ensure the positive (+) markings on the plastic connectors match the positive pins.
