• Trailer Taillights Malfunction When Vehicle Headlights are Switched On
• What you're describing is the classic symptom of a ground problem. Everything works fine until the headlights are turned on, which is when the maximum amperage is drawn through the system. That's when a ground problem will rear its ugly head. On the vehicle side of the equation, there's a white ground wire exiting the converter box. Make sure that's connected to clean, bare metal on the vehicle. If there's any corrosion or undercoating or dirt that's preventing the back side of that ring...

• Troubleshooting Lights Not Working with the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles
• You will want to check the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56002 to ensure that it is working properly.

If you have power going into the converter but not out, then there is something wrong with the wiring harness.

• The first place you want to check is the connector on your motorhome. I'm not sure if you have a 4-Way or 7-Way connector but I have attached diagrams of each for you to reference. Simply use a circuit tester like part # PTW2979 to verify that the left turn pin is actually receiving power.

• Reverse Lights on 2008 Lincoln MKX Stopped Working After Installing Curt Trailer Wiring Harness
• If you were to unplug the harness and plug the tail lights back in as normal do the reverse lights work then? If so then there is something wrong inside the wiring harness # C56329 and it will need to be replaced. You can also use harness # 118551. If the reverse lights still do not work then consult the vehicle owners manual for the location of the fuse and/or relay for the reverse lights and see if it has blown. If it has blown replace the fuse and if it blows again with the wiring harness...
