Recommended Replacement Brake Controller For Malfunctioning Hayes Genesis


my brake light keeps coming on. I disconnected the box and it was okay now I reconnected the box and it seems to be working fine. Do you think I may need a new one. The wiring is new and the trailer. The box however is approximately 7years old.

I see that you had the same issue with your Hayes genesis brake controller # HA81790 before. From the troubleshooting you have done and finding the controller seems to be working now, it sounds as if it is an intermittent issue that may reappear. I recommend replacing the brake controller.

I recommend the Prodigy P3 # 90885. This is our most popular brake controller because it is easy to set up and operate.

If you want to let me know the year make and model of your truck I can see if there is a plug-and-play harness for your truck.
