Hello Dan, thanks for reaching out. The best way to add a 7-way and brake controller to your 2017 Hyundai Santa Fe with an aftermarket 4-pin is by using the Universal Installation Kit # ETBC7. This kit contains everything you need to upgrade the 4-flat to a 7-way, including all of the necessary wires for a brake controller.
For the brake controller, the Tekonsha P3 # 90195 is what I recommend. It is easy to use and reliable. You can wire it in using the included universal pigtail.
What kind of trailer will you be towing.

Hey Jesse, I also have a 2017 Hyundai Santa Fe. I am towing an 2021 forest river Salem FSX 178BHSK. I just can't wait for the parts mentioned above. Anything I can get in the next few days?
