Which specific baggage claim carousels should I use to reach the SeaTac Rental Car Facility shuttle bus pick-up stops?

After arriving at Seattle-Tacoma International Airport (SEA) and collecting checked baggage in the Main Terminal, travelers bound for the consolidated SeaTac Rental Car Facility must board complimentary shuttle buses at one of two fixed pick-up points on the Baggage Claim level. Each stop is reached only by exiting the sliding glass doors positioned immediately beside specific baggage carousels at opposite ends of the claim hall—do not use general curbside exits elsewhere in the terminal. The North end stop is located next to Baggage Carousel #1 at the north end of the baggage claim area. This zone commonly serves domestic arrivals, including many flights associated with Alaska Airlines and other carriers using the north side of the terminal. After retrieving luggage at Carousel #1, follow overhead and floor signage for Rental Car Facility shuttles, pass through the marked sliding glass doors, and wait at the signed boarding area on the lower outer roadway. The South end stop is beside Baggage Carousel #15 at the south end of the baggage claim area, where international arrivals and south-terminal carriers most often claim bags. Exit through the sliding glass doors adjacent to Carousel #15 to reach the south-side shuttle queue. The Port of Seattle operates this shared shuttle network free of charge, 24 hours a day, 365 days a year. Buses typically run every 10 to 15 minutes, with a ride of about 5 to 7 minutes covering roughly 1. 5 miles to the facility at 3150 South 160th Street, SeaTac, WA 98188. Plan on roughly 3 to 4 minutes of walking—about 200 feet—from your carousel to the curb. All on-airport rental companies use these same buses.
