How to fix an USB-C connector from a cable

Hi @c_krakenbytes

How it's wired might depend on what USB-C functions the cable was intended to be able to cater for.

Although there's only 9 wires (plus shielding) in the cable, it still depends on exactly which one of the 24 possible pin connections were being utilized as it seems as though it wasn't intended to use all the functions offered by USB-C .

No doubt there's the standard Voltage, Ground and data wires i.e. VBUS, GND, D+ and D-, (usually Red, Black, Green and White).

From the image you posted it seems that there are at least 2 red wires so perhaps there's a red wire on the A4 pin and also on the A9 pin which are then connected to the B9 and B4 pins (allows the plug to be inserted either way). It may be the same if there are also 2 black wires in the cable i.e. A1 and A12 (B12 and B1) so that's 4 wires accounted for, plus the 2 data wires which makes 6 so you only have to identify 3 more.

Note: Use an Ohmmeter and check which pins the wires connect to at the other end of the cable just in case they used the same colour wire but not for the same purpose.

If you only need to be able to send/receive data and power a device with 5V only then connecting these 6 wires will suffice - see link below.

If you want to utilize the other functions provided by USB-C then given that the cable's broken off a bit short ideally the best option would have been to open the plug housing to access the wires on the cable side of the pins and identify which wire goes to which pin and then wire it accordingly.

Here's the full pinout that may help.
