Using your wire strippers, strip the insulation off of both ends of the cut cable. You should see four wires: red, black, green, and white.

Step 3: Solder the USB Connector

Take your male USB connector and identify the pins. The pins should be labeled D+, D-, VCC, and GND. Solder the black wire to GND, the red wire to VCC, the green wire to D+, and the white wire to D-.

Step 4: Solder the AUX Connector

Take your female AUX connector and identify the pins. The pins should be labeled left, right, and ground. Solder the green wire to left, the white wire to right, and the black wire to ground.

Step 5: Test the Cable

Once you’ve finished soldering, plug the USB end of the cable into a computer and the AUX end into speakers. Test the cable to make sure it’s working properly.
