Do you sell wifi card cable replacements for my model?
This is how I fixed the same issue on a 13” Pro some time back. Cleared from the insulation a small portion of the central wire of the two parts and soldered them together, put some UV curable rosin on the soldered part. Then I folded back the outer layer wires and soldered them together after folding the core wire. It can’t be straightened to avoid risk of shorting inner core/outer layers, thus it was just sandwiched between a couple kapton tape pieces. May not be very elegant but it worked out nicely in the end and it’s still working AFAIK.

The WiFi antenna is routed through the hinge along with the camera cable, which makes it impossible to replace without destroying the screen, you have to buy the whole top half of the computer.
