It is these poorly designed ports that are especially hard to see inside of while also trying to align the cable end with the port. Hence my suggestion of adding a small bit of a bend/dog leg to the last inch of the cable to allow it to be twisted about inside the frame, contact the sides of the frame while feeling for that exit. I hope this better explains my point. Andy.
