Hi Paul; for tow bar wiring I recommend the Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 7-Way to 6-Way Coiled Adapter Cord # RM-15267. Roadmaster makes really great, reliable wiring kits so they're my go to for flat tow setups. Since you have a 2024 Suburban you will also need the # RM-792. Two additional diodes are required starting in 2024. A battery disconnect # RM-766 is also needed as part of your setup.
We don't have instructions that are Suburban specific but there are GM specific wiring instructions for 2024 models like yours. See the pictures below.
