Adding a switch to flourecent lighting.
Hello, I have an issue I need help with please. I have four fluorescent light fixtures, each with two T8's, I would like to add a light switch to be able to turn off two of the four fixtures. They are currently operated by a motion sensor and I would still like that to be functional after the switch installation. Could I please get some advice on this project, specifically how to wire up the two fixtures so they can be turned off without effecting the other two fixtures. Thank you.
