The Curt Echo Wireless Trailer Brake Controller item # C51180 does need a dedicated power line to a 7-way connector to function. The only wire it does not require to be functional is the blue brake controller wire. To add a functional 7-way connector to your 2015 Kia Sorento LX I4 you will need two harnesses. The first is the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # 118583. This custom-fit T-One connector plugs into your Kia's wiring harness, which is located behind the driver's-side and passenger's-side tail lights.

The second harness you will need is the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires item # ETBC7L. The kit includes a pre-wired 7- and 4-way trailer connector that mounts easily at the rear of your vehicle with an included bracket. This kit is designed for use on a vehicle with an existing 4-way flat trailer connector and plugs directly into it. I have linked a couple of installation videos below.
