You have chosen a gorgeous trestle light over the island! It will hang where the center can is in this picture. However, two pendant light were previously wired to a switch.
So you have a couple of options:
1) Blank plate the pendant lights and paint the covers so they will be available should you ever want them in the future
2) Remove the pendant lights and drywall where they were wired and terminate their corresponding light switch.
There is no right or wrong answer just whatever is your preference.
Please let me know your preference.
