Since trailer wiring harness # 119178KIT is a universal fit type of item it does not have vehicle specific instructions. So the instructions are basically the same for all vehicles. You will use the included tester to test the tail light wiring on the vehicle then make the necessary connections.

White is ground and connects to a bare metal surface. Red is brake lights only, yellow is left turn signal only, and brown is running lights only. These are all on the driver's side. The green wire is for right turn signal only and goes to the passenger's side tail light.

I linked a video that shows how to test the wires. The wire colors are likely different on your vehicle so you will have to test them.
