Hi Matthew!
I see you already ordered the # ETBC7 wiring kit and Redarc Tow-Pro Liberty # RED52VR (sorry for the delay in this response) and I just wanted to confirm that you are good to go with what you will be receiving!
The # ETBC7 will piggyback off your existing 4-flat and has all the needed wiring and bits to run up to the battery and Liberty brake controller. I attached a diagram that will show how it should be done as well. Little bit of work, but not overly difficult.
Great choice going with Redarc as well. Their controllers are my favorite as I am 6'5" and tend to smack my knees into things, so I don't particularly like the ones that hang down into the footwell. Plus they work very well and you can only see the knob once installed. They nice.
Let me know if you run into any hiccups during the install. I am more than happy to help!
Oh, out of curiosity, what are you going to be towing with your 2023 Kia Telluride?
