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?

 
Solution
I see what you mean about the marked wiring now. The triangle indicates the positive end and looks like the wire with the white strips signified negative.
"Usually" the one with the stripe is signal and not ground.....but that doesn't necessarily mean that is the case here.

If you have a multimeter you can measure across the LED and this will tell you which is ground *the cathode of the diode would be connected to ground).

As far as the switch....it may not matter....but the LEDs matter.
 
Through the use of reading glasses combined with a magnifying glass I can see that the two pin connector in question (the reset connector) has a arrow stamped on the hard plastic end. That seems like that should mean something but darned if I know what.

Thanks for the replies.
Jay, I have the manual and did reference it when making these connections. My problem is that I cant clearly see what is positive and what is negative on the two pin connector.
Both wires on the connector are black and one of the black wires has a white stripe. Also at the end where the hard plastic connector is there is an arrow stamped into the plastic that indicates, according to SgtScream above (thanks for the reply SgtScream) means that wire is positive.

I dont even know that all of those indicators are consistent. I spent the better part of all morning trying to correctly attach these. At this point I figure Ill just have to wait and see what works and what doesnt at power-up. Fingers crossed.
 
Rocks1911....I kind of figured you looked at the manual....but just in case you didn't.

Also...as I eluded to earlier...I don't think you are going to screw anything up if you connect a switch or an LED backwards. A switch should still work backwards,,,,,and an LED just won't work backwards...but it won't hurt it.

What I wouldn't do is.....connect a switch where there's supposed to be an LED or vice versa.
