Question:

Hello, I have watched your video and installed the wiring harness just as your video shows how to. When I have my day light running lights on all my lights work. When I turn on my lights my drivers side brake light is alway on and it will not work if you press the brake or us the turn signal. Is there away that the curt box could be bad?

The issue you are describing sounds like a bad ground. I would first make sure that the white wire with the ring terminal on the Curt T-Connector Vehicle Wiring Harness part # C56208 is secured to a bare metal surface. If there is paint underneath the surface then you will want to take some 80 grit sandpaper and sand it down prior to attaching the ring terminal.

Once the ground is checked you will then need to make sure that the connectors are plugged into their respective sides. The connector with the yellow wire will plug into the driver side tail lights whereas the connector with the green wire will plug into the passenger side tail lights. It is also important that you check to make sure none of the pins are bent.

The converter box would likely not cause the issue you described so I recommend checking both the grounds and pins before moving forward. If these steps do not work then please let me know and I would be happy to provide further troubleshooting advice for you.
