When building a new PC.
Is there a way to find out which way round to plug in the HDD Led, Power switch, Power Led, Reset switch and Speaker connectors to the JFp1 and JFP2 connectors.
Most user manuals show you where they plug in, but they do not tell you which way round they go eg positive and negative etc.
Which of these connectors is it important or necessary to get them the right way round ?
Any suggestions ?
