If you have the owners manual look for towing section or fuse section.
You will need to identify the fuses needed to be installed for trailer circuits.

Then you would need 7 pin wiring harness from fuse box/brake controller to rear of Suburban (7 pin provides running lights, R & L turn/stop lights, backup lights, ground, trailer brake wire (from controller output) and trailer charge line)
That round plug MAY be a 7 pin or even a 6 pin (no charge line to trailer battery)
In addition to wiring harness, brake controller, brake controller wiring pigtail, a good hitch receiver........you would benefit from a tranny cooler and higher volume air intake filter along with 3:73 gearing
