i will be wiring my high tunnel for motorized endwall shutters. i read about the type of cable or conduit/cable to use. but i can't remember how to wire if i want the power source to enter the first vent motor's box then go to the thermostat and then on to the other vent motor. it should be like wiring 2 light fixtures with the switch in the middle and power source entering one of the fixtures before running to the switch.
