Need Inspiron 660s power button connector (LEDH1) pinout
I'm trying to help my friend's kid put his Inspiron 660s components into a new case (NXT Guardian 921), and need the pinout of the Power Button Connector (LEDH1) on the motherboard. Unfortunately I do not have the old 660s case at the moment to try and trace out the old wires. I have been able to successfully find a set of pins that works for the Power Switch, but cannot figure out which ones are for the HDD LED and the Reset Switch on the NXT case.
I also have a multimeter, but not sure what voltages I should be checking for, or if jumpers are used on the Dell pigtail connector.
