Looking for a cable to connect to diagnostic port

[Vader2]

I have been trying to find a cable that connects to the diagnostic port on the Apple Watch, but can't seem to find one. I can't believe there are none available - or even a pin out of the port so I could make one.

Does anyone know where I can find one?

You haven't called Foxconn?

I pretty much guarantee that Apple has not released that information.

Does anyone know where I can find one?

There is none available - at least available to consumers.

The diagnostic port is an interesting exercise, I suppose.
Did the original forum traffic ever find out anything at all? I don't remember ever seeing any reports about anything, other than possible quicker battery charging, but that was just a possibility.

Sounds like you are hoping to experiment with other uses for that port.
What do YOU have in mind?

You don't need to call Foxconn. You can open the watch with a screwdriver and attach a cable on the circuit board. iFixit have done this before

I don't think there's anything available commercially, however, I'm pretty sure it's been determined that it is a modified Lightning port, sans Pins 4 and 8.

So good luck with that knowledge OP
