That’s all it is. But I do see contact points next to the LEDs.
Perhaps a meter could be applied to those one at a time and see where it comes out on the other side.
Maybe even a voltage to light up the corresponding LEDS.
Need to think about that some.
But at least I can now quickly cull out the charge only cables.

Decided I’m going to mark all my USB-A cable ends with a “Top” decal.
I’m sick of the random markings that seem to be the way of these things.
All the Best,
Jeff
