Happy Sunday all!
I’ve got almost all of my house electrical sorted out in my 2003 Concourse upgrade. Before I spend time randomly testing wires, does anyone know how the water heater gets its power? I know its connected to the kitchen switch but haven’t figured out where that is tied into yet. Thanks.

Finally had some time to trace the wire. It gets its power from the hood monitor (grey on my 2003 concourse) dc wire.
