Installed new CD/DRD drive into Emachine, removed front panel and disconnected the 3 leads from motherboard without making note of which way they were connected! (idiot)

1 lead marked up HDD LED (must be hard drive light) red & white lead
1 lead marked up PRW LED (the main on light ) blue & white lead
1 lead marked up PWR S/W (the main swich) black & white lead

PHOTO PIN CONNECTIONS BELOW

In most situations, the power light is the top left two in the photo, the power switch is usually the two next to it and the hard drive light is underneath the power connector. Where a reset switch is provided it would go bottom right.

As for which way they go, power switch (and the reset switch as well) doesn't matter (since pressing the front switch completes the circuit and isn't dependent on any other factor hence why its possible to do it with a screwdriver) and if the lights are the wrong way round it doesn't hurt anything, the front LEDs just don't work. Positive (the non-white leads) is usually on the outside for the lights.

If in doubt, find the power switch first, it can only go in four places, the pin on its own probably doesn't do anything.
