You will need these if you have decided to delete the 4 wheel Steering from your Mitsubishi

These are installed into the steering rack directly, and blank off the hydraulic lines that run from from the Steering rack at the front of the car, to the 4WS at the rear.

Alternatively, they can be used to blank the lines at the rear end, for subsequent deletion of the front/rear lines, at a later date.

They can then be swapped to the steering rack.
