Helpful Expert Reply:

Most likely your problem is corrosion on the brake output circuit of the 7-way. I would inspect the 7-way on both your trailer and 2007 Ford F250 and clean the pins as necessary. I also attached an FAQ article on troubleshooting brake controller installs for you to check out as well.

You also can replace your factory brake controller if you like also. For more info on that check out the FAQ article I attached to the right.

For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.
