USB-C to lightning wiring diagram

Hello iFixers 🙌

I have two broken Apple Lightning cables. One is a USB to Lightning and the other one is USB-C to Lightning.

I'm more or less ok with the first one and it's wiring diagram - it has 4 wires just like the new replacement connectors I got from AliExpress 😁

However with a USB-C to Lightning I feel way less confident - this one has an additional blue wire and here I need your help - maybe someone could share a proper wiring diagram for this case?

Thanks in advance 🙏

P.S.:here are the pics of the new connector

@insympathy can you post an image of the replacement connector? For now what I have is

Red <==> Positive

White<==> D-

Green<==> D+

Blue<==> Listed as "CC" (maybe sensor wire for Apple's authentication IC (2V?)

Hey 👋 thanks for answering 👍

@insympathy you can't -) Pictures can only be added to answers and question. You did the right thing :-)

@insympathy looks like that connector doesn't have the connection needed for the blue CC line. You could try and solder the four cables without the blue one and see what happens. I thinks your Apple device may not like it because it can't verify that this is the "right" cable.

Did this work with the usb-c cable?

Because i used to customize the cables with paracord to make the more durable, but never did manage to venture to the usb-c ones.

@insympathy looks like you need a different connector or you could try to "rig it" but it would require some good soldering skills :-)

Here is what I get for the wires

If nothing else you get the USB-C pins from it:

Ground <==> pin 1

Red <==> Pin 9 VBus

White<==> Pin 7 D-

Green<==> Pin 6 D+

Blue<==> Pin 5 CC1

I have to replace the lightning end of a USB-C to lightning cable - what do I do with the blue wire? there only 4 pads on the replacement lightning tip and 5 wires. I have repaired several USB-A to lightning so I tried omitting the blue wire but no joy.

if you have a cable with 5 wires - you need a connector with 5 pins in order to support fast charging - those are also available on AliExpress
