Problem with Electrical Hand Brake

Hello. I have a Range Rover Sport 2.7 from 2006, i changed the electrical hand brake, but I don't know where should I connect the final cable from the electrical handbrake.

This is the controller of the car, and the final of the handbrake cable is in the red dot:


This is the final cable:


Now.. the question is : Where should i connect that final cable ?
P.S.: I had to change electrical handbrake box (the box that is over the rear diff.) and that's why i don't know where that cable fits.

Thank you!

Isn't that the emergency handbrake release cable?

When the electrics fail you pull hard on it to release the brake?
