The Tekonsha ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT includes a circuit tester that allows you to confirm which lighting signal is carried on each of the vehicle's wires. Since auto makers do not consistently use the same wire color for all production runs it is necessary to test to ensure you make the correct connections. The linked video shows how a tester works.

The included circuit tester allows one person to test the vehicle wires while another simultaneously engages the brakes, headlights and turn signals (one at a time, of course). Once you find the function carried on each vehicle wire installation is simple. You can refer to the linked installation video and to the liked instructions for more.
