It is located on the top of the dryer, which is located in front of the radiator on the left-hand side of the front of the van. The dryer is an aluminum cylinder that is about 5-7 inches tall and appx. 3 inches wide. There is an electrical wiring harness going into the top of the dryer. That harness is going into the pressure switch. It's not just a low pressure switch - it's a three-way switch with low, high and medium switches.
You can find a AC pressure switch wiring diagram, for your Kia Sedona, at your local Kia dealership. You can also find the diagram at most auto-parts stores.
