Can someone help with this? This usb tip had all the wires except two barely hanging on. I re soldered the red, white and blue properly back on the positions but I am confused with the yellow and black as there is only one hole left. My knowledge on this stuff is very very basic so I appreciate anyones input.

Thanks

Fug. That plug is fugged. Get a new cable if possible, that doesn't look salvageable, and it looks like you munged the pins on the left with a big solder pool bridging them anyway?

What he said. With the amount of heat damage it's showing, there's probably too much internal damage for it to ever work again.

Get a new plug, and solder it on by the extension wires. Keep the iron away from the plug casing.

The extra wire is probably ground and goes to the plug exterior. Can't say since I don't usually do USB (not worth the effort - buy a new one for a couple bucks)

Where would one get a replacement cord like this? with a usb tip, then I could just solder the ends of the wires to the circuit board itself

Why not just get an inexpensive USB cable and splice what you got into it? It should work even with out solder, tho you could always add it for stronger connection.

you really don't have any USB accessories or cables you're not using? I have like 5 in every room of my apartment and a couple in the car.

i'm gonna go out on a limb and say you probably don't need the yellow wire. try hooking it up with red to red, white to white, green to blue, and black to black.

After looking over some USB pineouts I think this might be a bad idea. There are so many variations there's no way of knowing if what you're using will work properly.

OP here. Okay so I tried splicing another usb end to the device, leaving the yellow wire out as someone mentioned. And it powered on. however a notice popped up on the computer saying the device has malfunctioned and the has exceeded its power for the port i should disconnect now.

Any ideas?

All the wiring diagrams I can find show only 4 wires. So as long as it matches on both ends it should be fine.

What's at the other end of your cable? Another connector or direct to device?

Diagrams usually omit shield ground.
