Electrical wiring for Air Conditioner (Swamp Cooler)

BeakAugust 24, 2012

The house is 21 yrs old. In the wiring box there are two sets of wires. The first set has red, black, white, and orange. The second set has white and black. There are two switches. The first switch controls the water pump and the ac motor. The second switch control hi/lo ac speed. I am a bit confused on the wiring and need some advice. Not sure which of the sets of wires to use for what. I suspect there needs to be a wire that goes from one switch to the other. Also not sure which would be the ground. Help. Thank you - Jerry
