Brake Controller and 7-way Trailer Connector for 2020 Kia Telluride

Good afternoon. I need to purchase everything I will need to convert the 4 pin factory installed hitch and wiring to a 7 pin system in order to give me trailer brakes to bring the towing capacity up to the advertised 5000 lbs. can you please help with exactly what I may need to do this. I plan on towing a travel trailer that is around 3200 uvw that will probably be closer to 4000 lbs after it is loaded with gear, food and luggage etc. the vehicle came with a 4 pin and I need to convert it to a 7 pin. I’m not sure if I will need a brake controller as well so maybe you can help me with that. I have never towed something this heavy that required trailer brakes so I just want to make sure my setup is going to be safe and wired up correctly. Any help would be much appreciated. Please help with all the accessories I would need to buy to make this happen. Thank you!
