Question:

This was my question: I bought Tow Pro Liberty brake controller and TPH-014 harness. My Pathfinder 2014, has CAN BUS system and the connector for the trailer so with this harness I can connect the controller to my car. Do I need to buy and install CBK30-EB 30A circuit breaker or this one is already factory installed on my car? Thank you Michael, My Pathfinder has the factory 7-way trailer connector. If I understand, to install 30-amp circuit breaker, I have to cut and remove the black wire from the harness #RED39FR-TPH-014 from white connector and connect it directly to the battery by the 30-amp breaker. Please see the picture and let me know if this will be ok! Thank you for your answer!

Helpful Expert Reply:

Yes, per the installation instructions, your 2014 Nissan Pathfinder with the Controller Area Network, or CAN Bus system, it is recommended by the manufacturer that you use the 30-amp circuit breaker kit # 331-CBK30-EB. This, along with your Redarc Tow-Pro Liberty Brake Controller, # RED24FR and the Plug-and-Play Wiring Harness for Redarc Tow-Pro Trailer Brake Controllers, # RED39FR (TPH-014) will have you all set. As long as your Pathfinder has the factory 7-way already. However, to add a 7-way to your Pathfinder, if needed, then you can do so easily with the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector, # C56357.

Yes, the diagram is correct. Please also note the attached "official version" from installation instructions. Only the black wire needs to be pulled from the TPH-014 and run to the battery with the breaker fit inline. The remaining wires within the TPH-014 can be left in place and the Tow-Pro harness plugged into the vehicle trailer brake connector. I verified this with the Redarc too just to ensure.
