From the connector pinout we can follow the traces

Pin 1 (with white dot) - Pin 4 : These go to three traces in the flex PCB, and go towards the sensor. Pins 2 and 3 are joined.

Pins 5-8 : These go to the stepper motor. Pins 5 and 7 appear to be one winding, and pins 6 and 8 the other winding.

The wider copper strips on the outside and middle are not connected.

Flex ribbon details:

0.07mm thick. There is at least 1mm gap between the focus elements and the inner barrel wall.

Stiffener thickness (at end with gold fingers) 0.30mm

As there are two weak spots (orange boxes) in the cable, the repair needs to run from before the first to after the second.
