ABS Trailer Brake Idiot Light... 2008 ProStar

[preacherboy24]

Had the same problem. The ABS wasnt getting the power from the right source and the brake light circuit was powering up the abs.... weird. It was a problem in the trailer harness. I have heard there was a trailer manufacture that routed the harness wrong in the 5th wheel plate area. It was rubbing an area that needed a grommet. My problem was harness rot in the rear of the trailer. It would only happen if I ran through snow and had snow buildup on the harness pulling it down.
