Short for Power LED, PLED is a connection on the system panel header labeled PLED, PLED1, or PLED2 that lights the Power LED (Light-Emitting Diode) indicators on your motherboard or case. In the picture, the motherboard LED is labeled as PLED2, which corresponds to its connector.
In the following example of a system panel connector, the PLED is a three pin connector. The top-left corner of the panel connector is positive (+), and the negative (-) wire is at the right.
