Lightning to USB cable: USB-C to lightning wiring diagram

Tue, 20 Jan 2026 06:15:12 -0700

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

Hi,

I frequently have lightning connectors that don"t reliably connect to an ipad or iphone and it seems like the surfaces of the connector are worn down. Is there a way to restore the surface to make a reliable connection again?

Lightning to USB cable: Why are there 8 cables in that Lightning extension?

Fri, 16 Aug 2024 16:12:47 -0700

I'm looking at a Lightning extension cable (with a female plug on one end and a male plug on the other) .

I would like to solder it to a standard Lightning cable (the 8 pin plug) which has 4 cables in it.

But if you look at the photo of the extension, there are 8 cables, in the following order:

black - white - green - yellow - red - purple - orange - blue

The standard 8-pin has 4 cables: gray - green - white - brown

It seems I have to solder every pair of cables from the extenion, to one cable from the 8-pin end.

But which combinations of colors should it be?

Lightning to USB cable: Need help figuring which wires to connect for charging

Tue, 11 Jul 2023 22:23:48 -0700

I am doing an experiment and trying to connect a usb c part of an iPhone charger cable to a usb a part. When I opened the charger that had a USB c, it didn't look like anything I have seen before (has 1 blue, 1 white, 2 copper, 1 green, and 4 uninsulated wires.) the usb a part has the standard (1 white, 1 red, 1 green 3 uninsulated)

which wires do I connect for charging? and which wires do what? (like ground, data -/+ etc) I cannot connect the wires to the port because I do not have to materials to do that.

Lightning to USB cable: Power cable repair help

The cable had damaged rubber near the top so I fixed it with some electrical tape. It wasn't a good fit though so I tried to take it off and reapply it though when removing the tape the cable came with it. I put tape over the effected area though now only chargers for a few seconds at a certain angle.
