As far as I know, we don’t have any schematics available for the Lightning flex.
Image 1: I don’t know what this IC does.
Image 2: Hoo boy, that’s a sloppy looking flex. The passives (resistors?) don’t even seem to be properly soldered on or barely making contact with the pads. These are inline with the connector pins; I’d be surprised if this flex worked at all.
Image 3: This looks better, these passives are involved in the microphone circuit.
