The number one electrical problem of our beloved 911s is poor grounds. That one looks bad. Strip the insulation back and get a solid connection, and use a new lug, and clean the bolt and connecting surfaces.
One truism is very accurate, it is impossible to have "too good" of a ground. More is always better.

It is the coax shield for the coil and points signal wires. They get grounded to the coil base and by the distributor.
It is “janky” looking for sure, but if they have continuity to the ground tab connector at the CDI they are working. Porsche used that style of coax for the 3 pin CDI wiring from the 73.5 up to the 77. Then they went to the 6 pin CDI. The earlier CDI harnesses that were run separately in earlier years was much more robust.
