Can you make a USB-C to USB-C cable from 2 USB-C to Lightning cables?

With several old USB-C to Lightning cables and now no need for the lighting side of them, is it possible to cut off the lighting ends of two cables and splice them together to make a longer USB-C to USB-C cable?

It seems like with the circuitry and resistors already in place on the factory USB-C ends it would be a simple strip and solder job on the corresponding wires, but wanted to check with wiser minds here before trying.

Hi @spiralingshape

Here's a link showing the pinout for a USB-C cable.

This should help you to wire a USB-C connector in at the other end of the cable.

Not sure what you mean by "...with the circuitry and resistors already in place on the factory USB-C ends..." though.

There's only wires in the cables unless you meant in the USB-C controllers in the devices that they connect to.

Thanks! Regarding the ends of the cable, I assume there is circuitry in there to manage power and data properly. I also assume that if those ends are left alone (only splicing wires in the middle one-to-one) everything should function correctly. Just making sure I'm not missing something that might be in those cables that wouldn't allow for this type of combining.

@spiralingshape

All the power management is done by the USB-C controllers in the devices depending on what wire has a signal on it from the other end.

Click on the link underneath the pinout for more information about specific USB-C cable types as they can vary.

Just make sure that you don't reverse any connections i.e. wrong wire on wrong pin when testing from end to end

Thanks, I saw that one, but since this isn't touching the ends of the cables, only soldering the wires in the middle, I wasn't sure if it was as simple as that or if there were any considerations about the cable functioning properly.
