Take the mounting bracket off of the card by unscrewing the two screws holding it in.
Remove the LED block using the solder wick and pliers. It might be a bit difficult to get off. Patience is a virtue here, pull too hard and you can break your card. If there are pieces stuck in the holes, get a pin and try to poke it out. Be careful not to damage the circuit traces.
Resolder a new LED into the ACT led holes, taking note which pin is the positive and which is the negative. The card will have a + marked on its positive hole, the longer leg is the positive line on an LED. You can attach wires to the hole and have the link LED off board as well, but I chose to keep it on board.
Solder the two wires onto the bottom side of the board as shown in the picture. I put the red wire onto the positive side and the black wire onto the negative for ease. Be sure none of the wires or solder are touching other pins when you are done. This can cause a short and possibly damage your board.
Attach the other ends of the wire to your other LED taking nore of the positive and negative wires. As said earlier, the longer leg on the LED is positive.
Reattach the mounting bracket onto the back of your card the same way as it was before you took it off.
