How to easily fit a Nissan Frontier with a trailer brake controller

After some trips with our Nissan Frontier, we have realized that it’s time to install a trailer brake controller. We knew this when we bought the truck.

For the controller, we went onto and looked at the available options. One looked good for our needs: the Redarc Tow-Pro Liberty Brake Controller.

While it was not the least expensive option available, we really liked that the control is just a knob that sticks through a blank plate in the dash and not a big unit that has to take up a lot of dash space.

A nice thing about this truck is that it has the factory tow package, so this would be just an easy plug-and-play install using the included wire harness.

Install took less than an hour from start to finish.

Did the truck already come with a 7 pin trailer connection at the rear bumper? Mine didn't but it came with the harness on the frame for one to be added. I ended up needing to cut and switch two wires in the 7 pin so that my trailer brakes weren't on constantly. E trailer said this was a common issue with the Nissans and the 7 pin harness, if it's that common I don't know why there hasn't been an update..

My truck came with the 7 pin from the factory and I have not yet had any issues with it.

Mine came with the 7 pin (2007).  A 7 to 4 pin converter plug is about $35.

I picked up one of those too. Comes in handy more times than I expected it would.
