I've got these pancake plugs and some cable. I tried my first one today and I got the ends of the cable stripped, the shielding negative coppery stuff twisted and tinned, and then the middle positive stuff twisted and tinned. Then I started soldering the two coppery strands to different parts of the plug when I figured out I have no idea where to solder what.
So like an hour later, I never got the cables to work

So can you tell me which tab is what? Like tip/ring/whateva and then which one the positive side goes? And then how and where to ground the negative side?
And can someone tell me what grounding is? I have no idea. im hopeless
