Hello Kenneth; since it sounds like you don't have the factory tow package you need the Curt T-Connector Vehicle Wiring Harness # C27BR. This plugs into the connection points behind your rear tail lights and will give you a 4-way to power your trailer's signal lights. If you don't already have one, you will also need a hitch like the # DT42GR and ball mount # C45534 for towing.
