@Viv, pls see pics.
This cable is originally an outboard gear shift item, 6 ft long with on both sides a 5mm thread with counternut. I had to make for my me one side a longer terminal at my YAMAHA boatmotor.
Easy:
-take 10mm alu rod
- cut lenght as neccessary
- tap an 5mm thread in one end
- adapt the other end to your needs ( hole, oval, square, etc)
Opening those crimpings do not lead IMO to success, because of lack of a new "press" terminal.
