I replaced my IDE hard drive in my eMachine computer and accidentally disconnected the jumpers Power Led, HDD Led and Power SW and would like to connect them back correctly.
How can I fix it?
System: Windows 7, hard drive IDE Maxtor

1Check your motherboard manual is what I would suggest first.– CaldeiraGCommented Oct 11, 2019 at 14:25

I always take a picture of stuff like that before disconnecting, unless there is a manual from emachines you are out of luck.– MoabCommented Oct 11, 2019 at 15:08

2There are multiple eMachines PC models with multiple motherboards. Without the model number, we can't find the right set of instructions to show you how to reconnect those wires. Please provide the model number printed on the same sticker which has the serial number, then click edit and add that essential information to the question. Please do not use Add Comment; instead use edit.– K7AAYCommented Oct 11, 2019 at 20:15

1) Using the model number of the PC, look up its hardware and maintenance manual at the manufacturer's website. Find the pins on the motherboard to connect the wiring to.
2) Wiring for LEDs is often color coded, because LEDs need to be connected with the correct polarity to work. They won't break if reverse the wiring, so if the wires are not color coded, you can try the wires in one position, and if that does not work, reverse them to try reverse polarity.
3) The Power Switch wires do not care about polarity; the power on circuit on the motherboard will accept its wires regardless of polarity.
