They are mounted on a special bracket located under the dashboard near the pedals. Accessing them is extremely difficult. First you need to open the trinket box and unscrew the two screws with a screwdriver.
Then, overcoming the resistance of the three clips, remove the lower trim from the dashboard, release it from the bonnet lock drive and remove it completely.
In the space that opens, you need to find the desired bracket.
