Adding remote lights to a flood light.

So I have a sensor that has failed that drives some sconces near the garage doors.

They have LED bulbs in them so they aren’t taking bunch of power,

I would like to have those sconces come on and off with the floodlights of the floodlight cam that I would like to use to replace where the motoin sensor was.

The spot light cam has an easy provision for that, but how about the floodlight cam? Do I just cut open tthe wires to the flood lights and slice in there?
