You can use the Curt T-Connector 4-Pole wiring harness # C55384 plugged in at the back of your existing factory connector to provide a 4-pole plug for your lighted hitch cover. This harness connects inline between the existing connector and the factory wiring. The factory connector at the bumper remains active.

A 4-Way trailer connector has the basic lighting functions only; running lights, left turn signal and brake lights, right turn signal and brake lights, and ground. A 7-Way has these functions and a 12 volt circuit, a circuit for electric trailer…
