Cable colours & positions on mainboard

By Sleafordtown ·
I was looking at my mainboard and accidentally pulled out the cables for the switch and LED connectors on the FPI Connector pins. There are 10 pins on the mainboard and I can see the general order that the cables go back on this connector but not which way the connectors fit - eg HD LED has two pins with one red cable and one white cable to go on pins 1 and 3. I put the connectors in as i thought best and I powered up my pc. The manual says the HD_LED P is pin 1 and HE_LED N is pin 3.
Now there is no light at all on the HD LED display at the front of the ATX case but the pc works fine. All the other LED lights are green at the front of the case.
Where can i find out about the cable colours and exact positioning of them?

Cable colours & positions on mainboard

Very few motherboard manuals specify the polarity (orientation) of the front panel connectors.

Part of this is because the case manufactures do not follow a specific color code standard. So, each brand of case may be different.

Start by finding the manual for the motherboard.
If this is a name brand system, you will need to search the manufactures web page.

If this is not a name brand system, and you need help identifying the motherboard to get the manual, check out the tools at either www.wimsbios.com
or www.motherboards.org

Make sure the HDD lamp plug is on the correct pins.
If it does not light up, just flip it over, and plug it back in.

I've been assembling PCs for years, and do not have a fool-proof method to identify the front panel cable orientations.
