The Switch is connected to the trunk hook . You do not have to remove the hook just the switch .
First you remove the plastic piece and the carpet that covers up the area .
Then with a angle phillips screw driver you unscrew the switch from the hook .
This is a example on how you would do it .
Then you remove the plug from the old switch then you clip on the new switch to the plug
Then you put every thing back together and test out your trunk light .
