Any time you want to add a shut off switch to a component you need to interrupt the power supply or the ground.
I highlighted both wires. The way to do this is cut one of these wires and run a new wire for each side of the wire to a toggle switch. This way when you flip the switch on, it will complete the circuit but it will keep the circuit open when the switch is off. I diagrammed it on the last sheet using the ground wire but either wire will work.
Let me know if you have questions. Thanks
