In order to use the reverse lights on your trailer, you will need to add a 4-Way to 5-Way adapter like # 47515. Using a circuit tester, like # PTW2993, find the wire behind your taillight assembly that carries the reverse light signal. It will have a signal when the vehicle is in reverse. Make sure you have someone in the vehicle to help you and put the emergency brake on for added safety. After you have found the reverse light wire, you can connect it to the Adapter 4 Pole to 5 Pole Trailer Wiring Adapter, # 47515, using the included quick splice. Then plug in the 4-Way to the back of the adapter and you will have a 5-Way connection with reverse light circuit.
