The Upgraded Circuit Protected Taillight Converter with 4 Pole End, item # 119178KIT, is the correct wiring harness for your vehicle. You will need to use a circuit tester, item # PTW2993 if needed, to find the correct circuits to splice the trailer wiring to. This harness will convert your vehicles 3 wire system to a two-wire system for the trailer.

Your vehicle does not have a multiplexed system so your taillight circuit and stop light circuit should be on separate wires.

Use the circuit tester and find the stop light wire on the drivers side behind the taillight and attach the red stop wire on the vehicle side of the converter to it then find the left turn wire and attach the yellow wire to this circuit, find the taillight circuit and attach the brown wire there. Finally run the green wire to the passengers side of the vehicle and attach it to the right turn signal circuit behind the right taillight.
