If you have the Hopkins Plug-In Simple Vehicle Wiring Harness for Factory Tow Package # HM43385, the harness will plug directly into the factory plug at the rear of the vehicle near the bumper. You will not need any additional wiring in order to get this installed.

If you do not have a factory tow package on your vehicle, I recommend # C59496 and # ETBC7. These will come with everything that you need to get them installed.
