This is the situation we have in our detached garage.
We are attempting to run 4 lights on one circuit with 2 separate control switches. (Not 3-way). All wire is 14/2.
Power from panel comes in to light #1. Light #2 is fed from light #1. These two lights will be controlled by switch #1. Cable from light #1 goes to switch #1
Light #3 is fed from light #1. Light #4 is fed from light #3. These two lights will be controlled by switch #2. Cable from light #3 goes to switch #2.
We need a wiring diagram for hooking this together is possible.
