alan0043 Posted March 31, 2016 Report Share Posted March 31, 2016 Hi Everyone, I have installed a Hayes controller. It is air actuated. Today is the first day that I could start up the truck from when I installed the controller. The problem is when I release the brakes on the truck that the manual lever on the controller will move to the right and the LED light will come on. I believe that the trailer brakes are being actuated when this happens. The only thing that I can think of, did I tap into the correct air line for the brakes. The line that I tapped into has a plastic part with 2 wires coming off of this plastic part. This plastic part is at the end of this air line. I placed a tee in this air line. And the one end goes to the controller and the other end goes to this plastic part. I was hoping that plastic part was the brake light switch. Were do I start looking ? I want to be on the road for the ECR by April 7th.. Thank for any help, Al Link to comment Share on other sites More sharing options...
