On my Strix Z370 - E mobo Im connecting very tiny leads (system power LED, HDD activity LED, power button, etc. and the manual (yes Im reading the manual, this is my first build and Im old and half blind) indicates that the ground wire must be oriented correctly. The problem is that the wiring is all black and there is no indication which is the ground. Of the two wires involved both are black but one has a tiny white stripe that runs the length, would that be the ground?
