I have attached a basic brake controller wiring diagram for you. You will want to make sure that you ground the white wire to the negative post on the battery. The black wire will attach to the positive battery post. The red wire will tap into the stoplight switch on your vehicle's brake pedal. The blue wire will run back to the trailer connector. The brake controller will come with the universal 4-wire harness.
I have also linked the installation directions for the Tekonsha Voyager # 39510.
Many times, you will be able to use a direct fit wiring harness to attach your brake controller with your vehicle's wiring harness if your vehicle came with a factory tow package. If you will send me the year, make, and model of your vehicle, I will be happy to see if you are able to use a direct fit wiring harness. With this information I can also provide a specific parts list and instructions for your vehicle.
I have attached two articles with brake controller information for you.
