You have to know which ter.inal they're coming into however that airport is set up so you can go to a specific location and have your ride pick you up at a place of your choosing. Foe example if you want easy access to the freeway you tell your ride to pick you up at the corresponding door number. It's was easy and I'm not an expert traveler.
South terminal, then follow the signs. It will literally take you to the passenger pick-up.
You have to find out what terminal they are arriving in and you can literally drive up and get them but you have to know what terminal it is, they can find that out with a little investigation.
